The medical science concerned with the prevention, diagnosis, and treatment of diseases in animals.
An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

High-throughput screening of small molecules in miniaturized mammalian cell-based assays involving post-translational modifications. (1/32616)

BACKGROUND: Fully adapting a forward genetic approach to mammalian systems requires efficient methods to alter systematically gene products without prior knowledge of gene sequences, while allowing for the subsequent characterization of these alterations. Ideally, these methods would also allow function to be altered in a temporally controlled manner. RESULTS: We report the development of a miniaturized cell-based assay format that enables a genetic-like approach to understanding cellular pathways in mammalian systems using small molecules, rather than mutations, as the source of gene-product alterations. This whole-cell immunodetection assay can sensitively detect changes in specific cellular macromolecules in high-density arrays of mammalian cells. Furthermore, it is compatible with screening large numbers of small molecules in nanoliter to microliter culture volumes. We refer to this assay format as a 'cytoblot', and demonstrate the use of cytoblotting to monitor biosynthetic processes such as DNA synthesis, and post-translational processes such as acetylation and phosphorylation. Finally, we demonstrate the applicability of these assays to natural-product screening through the identification of marine sponge extracts exhibiting genotype-specific inhibition of 5-bromodeoxyuridine incorporation and suppression of the anti-proliferative effect of rapamycin. CONCLUSIONS: We show that cytoblots can be used for high-throughput screening of small molecules in cell-based assays. Together with small-molecule libraries, the cytoblot assay can be used to perform chemical genetic screens analogous to those used in classical genetics and thus should be applicable to understanding a wide variety of cellular processes, especially those involving post-transitional modifications.  (+info)

Hybrid capture II, a new sensitive test for human papillomavirus detection. Comparison with hybrid capture I and PCR results in cervical lesions. (2/32616)

AIM: To test a new assay for the detection of human papillomavirus (HPV) DNA, hybrid capture II (HC II), compared with the previous commercialized hybrid capture I (HC I) and polymerase chain reaction (PCR) results on cervical scrapes from fresh cone excision biopsy samples. METHODS: The three methods were used on cervical scrapes from 42 fresh cone excision biopsy samples. There were nine metaplastic and inflammatory lesions, five low grade lesions, and 28 high grade lesions. PCR was performed using the general primers GP5+/GP6+. The viral load of high risk HPV DNA was estimated by the ratio of relative light units to positive control values in the samples. RESULTS: The sensitivity of HC I for the detection of high grade lesions was 71.4%, while it was 92.8% for HC II and 96.4% for the PCR. Considering only the absence of detectable cervical in situ neoplasia, the specificity was 88.9% for HC I, 66.7% for HC II, and 66.7% for PCR. With HC II, for a ratio of cervical sample to normal control of > 200, the sensitivity for the detection of high grade lesion was only 34.6% with a specificity of 66.7%. CONCLUSIONS: HPV detection with the HC II assay is more sensitive than the previous HC I and represents a more convenient and easier test than PCR for routine use. Nevertheless the viral load estimated with this test cannot be a reliable predictive indicator of high grade lesions.  (+info)

Helicobacter pylori infection, garlic intake and precancerous lesions in a Chinese population at low risk of gastric cancer. (3/32616)

BACKGROUND: Cangshan County of Shandong Province has one of the lowest rates of gastric cancer (GC) in China. While intestinal metaplasia (IM) and dysplasia (DYS) are less common in Cangshan than in areas of Shandong at high risk of GC, these precursor lesions nevertheless affect about 20% of adults age > or = 55. SUBJECTS AND SETTING: In order to evaluate determinants of IM and DYS in Cangshan County, a low risk area of GC a survey was conducted among 214 adults who participated in a gastroscopic screening survey in Cangshan County in 1994. METHOD: A dietary interview and measurement of serum Helicobacter pylori antibodies were performed. RESULTS: The prevalence of H. pylori was lowest (19%) among those with normal gastric mucosa, rising steadily to 35% for superficial gastritis (SG), 56% for chronic atrophic gastritis (CAG), 80% for IM, and 100% for DYS. The prevalence odds of precancerous lesions were compared with the odds of normal histology or SG. The odds ratio (OR) or CAG associated with H. pylori positivity was 4.2 (95% confidence interval [CI] : 1.7-10.0), while the OR of IM/DYS associated with H. pylori positivity was 31.5 (95% CI: 5.2-187). After adjusting for H. pylori infection, drinking alcohol was a risk factor for CAG (OR = 3.2, 95% CI: 1.1-9.2) and IM/DYS (OR = 7.8, 95% CI: 1.3-47.7). On the other hand, consumption of garlic showed non-significant protective effects and an inverse association with H. pylori infection. CONCLUSIONS: The findings of this study suggest that infection with H. pylori is a risk factor and garlic may be protective, in the development and progression of advanced precancerous gastric lesions in an area of China at relatively low risk of GC.  (+info)

Functional activities and epitope specificity of human and murine antibodies against the class 4 outer membrane protein (Rmp) of Neisseria meningitidis. (4/32616)

Antibodies against the class 4 outer membrane protein (OMP) from Neisseria meningitidis have been purified from sera from vaccinees immunized with the Norwegian meningococcal group B outer membrane vesicle vaccine. The human sera and purified antibodies reacted strongly with the class 4 OMP in immunoblots, whereas experiments with whole bacteria showed only weak reactions, indicating that the antibodies mainly reacted with parts of the class 4 molecule that were not exposed. The purified human anti-class 4 OMP antibodies and the monoclonal antibodies (MAbs) were neither bactericidal nor opsonic against live meningococci. Three new MAbs against the class 4 OMP were generated and compared with other, previously described MAbs. Three linear epitopes in different regions of the class 4 OMP were identified by the reaction of MAbs with synthetic peptides. The MAbs showed no blocking effect on bactericidal activity of MAbs against other OMPs. However, one of the eight purified human anti-class 4 OMP antibody preparations, selected from immunoblot reactions among sera from 27 vaccinees, inhibited at high concentrations the bactericidal effect of a MAb against the class 1 OMP. However, these antibodies were not vaccine induced, as they were present also before vaccination. Therefore, this study gave no evidence that vaccination with a meningococcal outer membrane vesicle vaccine containing the class 4 OMP induces blocking antibodies. Our data indicated that the structure of class 4 OMP does not correspond to standard beta-barrel structures of integral OMPs and that no substantial portion of the OmpA-like C-terminal region of this protein is located at the surface of the outer membrane.  (+info)

Characterization of human bactericidal antibodies to Bordetella pertussis. (5/32616)

The Bordetella pertussis BrkA protein protects against the bactericidal activity of complement and antibody; however, some individuals mount an immune response that overcomes this bacterial defense. To further characterize this process, the bactericidal activities of sera from 13 adults with different modes of exposure to B. pertussis (infected as adults, occupational exposure, immunized with an acellular vaccine, or no identified exposure) against a wild-type strain and a BrkA complement-sensitive mutant were evaluated. All of the sera killed the BrkA mutant, suggesting past exposure to B. pertussis or cross-reactive organisms. Several samples had no or minimal activity against the wild type. All of the sera collected from the infected and occupationally exposed individuals but not all of the sera from vaccinated individuals had bactericidal activity against the wild-type strain, suggesting that some types of exposure can induce an immune response that can overcome the BrkA resistance mechanism. Adsorbing serum with the wild-type strain removed the bactericidal antibodies; however, adsorbing the serum with a lipopolysaccharide (LPS) mutant or an avirulent (bvg mutant) strain did not always result in loss of bactericidal activity, suggesting that antibodies to either LPS or bvg-regulated proteins could be bactericidal. All the samples, including those that lacked bactericidal activity, contained antibodies that recognized the LPS of B. pertussis. Bactericidal activity correlated best with the presence of the immunoglobulin G3 (IgG3) antibodies to LPS, the IgG subtype that is most effective at fixing complement.  (+info)

Overexpression of human homologs of the bacterial DnaJ chaperone in the synovial tissue of patients with rheumatoid arthritis. (6/32616)

OBJECTIVE: To study the expression of the chaperone family of J proteins in the synovial tissue of patients with rheumatoid arthritis (RA) or osteoarthritis. METHODS: Rabbit antibodies specific for a synthetic peptide (pHSJ1: EAYEVLSDKHKREIYD), representing the most conserved part of all J domains thus far identified--among them the Drosophila tumor suppressor Tid56--were used in immunohistochemical analyses of frozen sections of synovial tissue and immunoblotting of protein extracts of adherent synovial cells. IgG specific for Tid56 was also used. RESULTS: Both antisera predominantly and intensely stained synovial lining cells from RA patients; other cells did not stain or stained only faintly. In immunoblots, anti-pHSJ1 specifically detected several bands with molecular weights of >74 kd (type I), 57-64 kd (type II), 41-48 kd (type III), and < or =36 kd (type IV). The strongest band detected in RA adherent synovial cells was the type II band, whereas in a B cell line, a type I band was prominent. CONCLUSION: Several potentially new members of the J family are described. The type II band represents the human homolog of the Drosophila Tid56 protein and is strongly expressed in RA synovial tissue.  (+info)

Interferon-alpha does not improve outcome at one year in patients with diffuse cutaneous scleroderma: results of a randomized, double-blind, placebo-controlled trial. (7/32616)

OBJECTIVE: To determine whether interferon-alpha (IFNalpha) reduces the severity of skin involvement in early (<3 years) diffuse scleroderma. METHODS: In a randomized, placebo-controlled, double-blind trial, 35 patients with early scleroderma received subcutaneous injections of either IFNalpha (13.5 x 10(6) units per week in divided doses) or indistinguishable placebo. Outcomes assessed were the modified Rodnan skin score, as determined by a single observer at baseline, 6 months, and 12 months, as well as data on renal, cardiac, and lung function. Pre- and posttreatment skin biopsy samples were analyzed and blood was obtained for assessment of procollagen peptide levels. RESULTS: There were 11 withdrawals from the IFNalpha group and 3 from the placebo group due to either toxicity, lack of efficacy, or death. In the intent-to-treat analysis, there was a greater improvement in the skin score in the placebo group between 0 and 12 months (mean change IFNalpha -4.7 versus placebo -7.5; P = 0.36). There was also a greater deterioration in lung function in patients receiving active therapy, as assessed by either the forced vital capacity (mean change IFNalpha -8.2 versus placebo +1.3; P = 0.01) or the diffusing capacity for carbon monoxide (mean change IFNalpha -9.3 versus placebo +4.7; P = 0.002). Skin biopsy showed no significant decrease in collagen synthesis in the IFNalpha group, and no significant differences in the levels of procollagen peptides were seen between the 2 groups. CONCLUSION: This study suggests that IFNalpha is of no value in the treatment of scleroderma, and that it may in fact be deleterious.  (+info)

Familial antiphospholipid antibody syndrome: criteria for disease and evidence for autosomal dominant inheritance. (8/32616)

OBJECTIVE: To develop diagnostic criteria for a familial form of antiphospholipid antibody syndrome (APS), identify families with >1 affected member, examine possible modes of inheritance, and determine linkage to potential candidate genes. METHODS: Family members of probands with primary APS were analyzed for clinical and laboratory abnormalities associated with APS. Families with > or =2 affected members were analyzed by segregation analysis and typed for candidate genetic markers. RESULTS: Seven families were identified. Thirty of 101 family members met diagnostic criteria for APS. Segregation studies rejected both environmental and autosomal recessive models, and the data were best fit by either a dominant or codominant model. Linkage analysis showed independent segregation of APS and several candidate genes. CONCLUSION: Clinical and laboratory criteria are essential to identify the spectrum of disease associated with APS. We believe a set of criteria was developed that can precisely define affected family members with APS. Modeling studies utilizing these criteria strongly support a genetic basis for disease in families with APS and suggest that a susceptibility gene is inherited in an autosomal dominant pattern. However, in these families, APS was not linked with HLA, Fas, or other candidate genes, including beta2-glycoprotein 1, HLA, T cell receptor beta chain, Ig heavy chain, antithrombin III, Fas ligand, factor V, complement factor H, IgK, and Fas.  (+info)

A novel double-antigen sandwich enzyme-linked immunosorbent assay (ELISA) was developed to measure rabies antibodies in dogs. G and N protein was synthesized and found to be immunogenic in mice (3), suggesting that the chimeric peptide derived from rabies virus may be used as a diagnostic antigen for detecting rabies antibodies. Iressa Two recombinant plasmids, pGEX4T2/ep and pET32a/ep, were constructed through the in-frame fusion of a chimeric peptide (AVYTRIMMNGGRLKRPPDQLVNLHDFRSDEIEHLVVEE) representing rabies G (amino acids 253 to 275) and N (amino acids 404 to 418) proteins to the C-terminal coding sequence of glutathione = 400) and unvaccinated (= 100) dogs and equally prediluted with sample diluent buffer (phosphate-buffered saline buffer, pH 7.4, including 4% [wt/vol] polyethylene glycol 6000, 3% [wt/vol] NaCl, 0.05% [vol/vol] Tween 20), were added to the wells in duplicate. The negative sera (collected from unvaccinated dogs that tested negative by neutralization test) were added in ...
Antibodies in porcine sera against glycoprotein E (gE) of pseudorabies virus (PRV) are usually measured in blocking enzyme-linked immunosorbent assays (ELISAs) with one or two murine monoclonal antibodies (MAbs) directed against gE. Our aim was to develop a confirmation assay which is based on another principle and which is able to detect antibodies directed against most potential binding sites on gE with high specificity. Therefore, we developed an indirect double-antibody sandwich assay (IDAS) using recombinant gE expressed by baculovirus (BacgE960). A fragment of the gE gene consisting of nucleotide positions +60 to +1020 of gE, coding for the major antigenic sites of gE but not the transmembrane region, was cloned behind the signal sequence of PRV gG and the p10 promoter in a baculovirus vector. Immunoblot analysis showed that the expressed protein reacted with MAbs directed against five of the six antigenic sites on gE. Although the conformation of some antigenic sites, notably antigenic ...
A simple, specific, high-throughput enzyme-linked immunosorbent assay (ELISA) for quantitative determination of melatonin was developed for directly measuring melatonin in cell culture medium with 10% FBS. This assay adopts a commercial monoclonal melatonin antibody and melatonin-HRP conjugate, so it can be applied in multiple labs rapidly with low cost compared with commercial RIA and ELISA kits. In addition, the procedure is much simpler with only four steps: 1) sample/conjugate incubation, 2) plate washing, 3) TMB color reaction and 4) reading of results. The standards of the assay cover a wide working range from 100 pg/mL to 10 ng/mL. The sensitivity was 68 pg/mL in cell culture medium with 10% FBS and 26 pg/mL in PBS with as little as 25 μL sample volume. The recovery of melatonin from cell culture medium was 101.0%. The principal cross-reacting compound was 5-methoxytryptophol (0.1%). The variation coefficients of the assay, within and between runs, ranged between 6.68% and 15.76% in cell ...
An enzyme-linked immunosorbent assay (ELISA) for pantothenate has been developed. Antibodies induced in rabbits against bovine serum albumin-pantothenate conjugate were specifically purified by affinity chromatography. This process served to reduce the amount of endogenous pantothenate attached to the antibody, as well as to purify the antibody. The purified antibodies were covalently linked to alkaline phosphatase (Sigma type VII) with glutaraldehyde (0.05% aqueous solution). An immobilized pantothenate substrate was first obtained by attaching human serum albumin-pantothenate conjugate to the surface of polystyrene culture tubes by passive adsorption. The binding of the enzyme labelled antibody (E-AB} to this substrate is proportionately inhibited by free pantothenate as standards or as samples for analysis. The inhibition of E-AB immobilization was quantitated at 405 nm by the hydrolysis of p-nitrophenyl phosphate as indicated by the formation of p-nitrophenol. A standard curve was plotted on log

AIDS was first recognized in the United States in the summer of 1981, when the U.S. Centers for Disease Control and Prevention (CDC) reported the unexplained occurrence of Pneumocystis jirovecii (formerly P. carinii) pneumonia in five previously healthy homosexual men in Los Angeles and of Kaposis sarcoma (KS) with or without P. jirovecii pneumonia and other opportunistic infections in 26 previously healthy homosexual men in New York, San Francisco, and Los Angeles. The disease was soon recognized in male and female injection drug users; in hemophiliacs and blood transfusion recipients; among female sexual partners of men with AIDS; and among infants born to mothers with AIDS. In 1983, human immunodeficiency virus (HIV) was isolated from a patient with lymphadenopathy, and by 1984 it was demonstrated clearly to be the causative agent of AIDS. In 1985, a sensitive enzyme-linked immunosorbent assay (ELISA) was developed; this led to an appreciation of the scope and evolution of the HIV epidemic ...

Activated monocytes play an important role in the pathogenesis of inflammatory arthritis. Blood monocytes which enter the inflamed joint become activated upon adherence to extracellular matrix and exposure to a complex inflammatory environment. We have analyzed the mechanism of monocyte activation by soluble factors present in inflammatory synovial fluid (SF). Greater than 75% of inflammatory SFs tested (a total of 22 fluids to date) increased cell surface expression and dramatically increased mRNA levels of monocyte activation markers Fc gamma RI, Fc gamma RIII, and HLA-DRA. This induction was not triggered by adherence, a known activating stimulus, and several lines of evidence showed that induction was not dependent upon interferon gamma (IFN-gamma). Induction was not prevented by neutralizing anti-IFN-gamma antibodies and IFN-gamma was not detected in the SFs using a sensitive enzyme-linked immunosorbent assay. The SFs also were not able to activate the IFN-gamma-activated transcription ...
Glucosidase II is an endoplasmic-reticulum-localized enzyme that cleaves the two internally alpha-1,3-linked glucosyl residues of the oligosaccharide Glc alpha 1----2Glc alpha 1----3Glc alpha 1----3Man5-9GlcNAc2 during the biosynthesis of asparagine-linked glycoproteins. We have purified this enzyme to homogeneity from the lactating bovine mammary gland. The enzyme is a high-mannose-type asparagine-linked glycoprotein with a molecular mass of approx. 290 kDa. Upon SDS/polyacrylamide-gel electrophoresis under reducing conditions, the purified enzyme shows two subunits of 62 and 64 kDa, both of which are glycosylated. The pH optimum is between 6.6 and 7.0. Specific polyclonal antibodies raised against the bovine mammary enzyme also recognize a similar antigen in heart, liver and the mammary gland of bovine, guinea pig, rat and mouse. These antibodies were used to develop a sensitive enzyme-linked immunosorbent assay for glucosidase II. ...

Streptococcus pneumoniae is a serious worldwide pathogen and the focus of numerous vaccine development projects. Currently the most widely accepted surrogate marker for evaluating the efficacy of a given vaccine is to utilize ELISA. Measurement of antibody concentration by ELISA without reduction in cross-reactive antibodies causes an overestimation of antibody concentration and therefore protection, this is most notable in the aged, an at risk group for this infection. We compared the immune response to the pneumococcal polysaccharides (PPS) 4 and 14 of 20 young to 20 elderly adults. Pre-and post-vaccination IgG antibody concentrations and antibody avidity against PPS4 and PPS14 were measured using two different enzyme-linked immunosorbant assay (ELISA) absorption protocols. All sera were pre-absorbed with either cell-wall polysaccharide (CPS), or CPS and serotype 22F polysaccharide. Pre- and post-vaccination IgG antibody concentrations for serotype 4, but not 14, were significantly lowered with the

For therapeutic monitoring and pharmacokinetic studies of lenalidomide (LND), the potent drug for treatment of multiple myeloma (MM), a specific antibody was required for the development of a sensitive immunoassay system for the accurate determination of LND in plasma. In this study, a hapten of LND (N-glutaryl-LND) was synthesized by introducing the glutaryl moiety, as a spacer, into the primary aromatic amine site of the LND molecular structure. The structure of the hapten (G-LND) was confirmed by mass, 1H-NMR, and 13C spectrometric techniques. G-LND was coupled to each of bovine serum albumin (BSA) and keyhole limpet hemocyanin (KLH) proteins by ethyl-3-(3-dimethylaminopropyl) carbodiimide as a coupling reagent. LND-KLH conjugate was used as an immunogen. Four female 2-3 months old New Zealand white rabbits were immunized with an emulsion of LND-KLH with Freund`s adjuvant. The immune response of the rabbits was monitored by direct enzyme-linked immunosorbent assay (ELISA) using LND-BSA immobilized

Background: Commercially available ELISA kits are popular among investigators that quantify faecal corticosterone or cortisol metabolites (FCM) for stress assessment in animals. However, in faeces, these assays mainly detect immunoreactive glucocorticoid metabolites. Since different assays contain antibodies of different origin, the detection level and cross-reactivity towards different metabolites and other steroids differ considerably between assays. Thus, the validity of one assay for FCM quantification in stress assessment is not necessarily the same for another assay. Materials and Methods: The present study was designed to investigate corticosterone (CORT) in serum and FCM levels in faeces of laboratory mice, as quantified in four different ELISA kits (DRG EIA-4164, Demeditec DEV9922, Enzo ADI-900-097 and Cayman EIA kit 500655). Assay kits were chosen based on the origin of the antibody, detection level and variation in cross-reactivity. Results: As expected, all four assay kits could ...
A novel minicolumn chromatographic method to monitor the production of inclusion bodies during fermentation and an enzyme-linked immunosorbent assay (ELISA) system allowing direct analysis of the particles with surface-displayed antigens are described. A 33-kDa protein containing 306 amino acids with three sulfur bridges produced as inclusion bodies was labeled with polyclonal antibodies against 15 amino acid (anti-A15) and 17 amino acid (anti-B17) residues at the N- and C-terminal ends of the protein, respectively. Labeled particles were bound to macroporous monolithic protein A-cryogel adsorbents inserted into the open-ended wells of a 96-well plate (referred to as protein A-cryogel minicolumn plate).

This publication describes the synthesis, silane functionalization and use of magnetic Iron nanoparticles in combination with enzyme-linked immunosorbent assay (ELISA) to facilitate the hybrid technique of magnetic nanoparticles - ELISA for use in the capture of progesterone in numerous types of milk. The synthesis and functionalization of the magnetic nanoparticles were carried out in an automated Globe system (now replaced by the Syrris Orb Jacketed Reactor) to furnish nanoparticles with a mean size of 182.4nm and 292.8nm after functionalization.. Abstract: A highly sensitive magnetic nanoparticle enzyme immunoassay of progesterone was established using horseradish peroxidase as a label. The enzyme label was prepared by coupling of progesterone-3-(O-carboxymethyl)oxime to horseradish peroxidase. The anti-progesterone antibody was immobilized on the amino modified magnetic nanoparticles by glutaraldehyde?. The typical standard curve for progesterone in the buffer by the magnetic ...
In this study we have determined the hepatitis C virus (HCV) serotype and genotype in a cohort of 96 HCV-infected hemophiliacs and have examined the relationship between HCV genotype and severity of chronic liver disease as determined by liver biopsy. HCV serotype was determined by specific enzyme-linked immunosorbent assays (ELISAs) and genotype by restriction fragment length polymorphism (RFLP) and HCV viral sequencing. The pattern of genotype distribution was quite unlike that of HCV-infected United Kingdom (UK) blood donors in that five of the six known HCV genotypes were represented, 50% were type 1, 13% type 2, and 18% type 3. An unexpected observation was the presence of HCV genotype 4 in four patients and type 5 in two patients. An additional feature was the presence of mixed infection, detected in 14% and 7% by serotype and genotype analysis, respectively. Liver biopsies were available from 51 patients. Cirrhosis was present in five of 27 (19%) of individuals with type 1, in 2 of 9 (22%) with

Cyclosporin A (CsA) is an immunosuppresor drug that has been used in the treatment of several types of inflammatory diseases. In some of them the inhibition of T-lymphocyte activation does not suitably account for the observed beneficial effect, suggesting that CsA could act on other types of cells. The present study was undertaken to determine the effect of CsA on inflammatory cytokine secretion by U937 monocyte cells. Undifferentiated and dimethylsulfoxide (DMSO) differentiated U937 cells were incubated with different concentrations of CsA (200, 20 and 2 ng/mL) in the presence or absence of phorbol-myristateacetate (PMA). Interleukin-1g (IL-1β), tumor necrosis factor-α (TNF-α), IL-6 and IL-8 levels were measured in supernatants using specific enzyme-linked immunosorbent assays. At the highest concentration used (200 ng/mL) CsA decreased the basal and stimulated secretion of all the inflammatory cytokines studied in both undifferentiated and differentiated cells, with the only exception
Background: Vascular endothelial growth factor-A (VEGF-A) plays a pivotal role in cardiac angiogenesis and is required for preventing the transition from compensatory left ventricular hypertrophy (LVH) to heart failure (HF). Vascular endothelial growth factor-C (VEGF-C), a homologue of the VEGF family, plays a key role in lymphangiogenesis. However, the relationship between VEGF-C and HF is unknown.. Methods and Results: We carried out a cross-sectional study involving 401 outpatients whose New York Heart Association functional classes were stable for at least 3 months. We performed echocardiography and calculated the left ventricular ejection fraction (LVEF) and left ventricular mass index (LVMI). Serum levels of N-terminal pro-brain natriuretic peptide (NT-proBNP), VEGF-A, and VEGF-C were determined employing specific enzyme-linked immunosorbent assays. Patients were divided into three groups: those with systolic dysfunction (HF+; LVEF , 50%), those with LVH and a preserved systolic function ...
Field research in remote areas presents many challenges, often including a lack of facilities and resources for maintaining a cold chain to preserve samples at low temperatures until they can be assayed in a laboratory. Cold-chains are necessary for the storage and transport of many types of biological samples (e.g., blood, urine and saliva) in order to reduce degradation and inhibit bacterial and fungal growth. One alternative to a cold chain is to add sodium azide, a potent antimicrobial, to each biological sample. However, sodium azide is incompatible with commercial enzyme immunoassay (EIA) kits that use horseradish peroxidase, an enzyme inactivated by sodium azide. To address this problem, we tested and validated EIA protocols that use an alternative enzyme, alkaline phosphatase. These protocols can be used for the measurement of steroid hormones in salivary samples that have been preserved with sodium azide, thus eliminating the trouble and expense of maintaining a cold chain from the ...
Analysis of anti-arboviral IgG in patient sera by using the ELISA format has previously been reported (2). When inactivated antigens are applied as a coating directly onto a plate, nonspecific background reactions occur (7). To avoid this problem, IgG ELISAs have been developed as either indirect assays, in which purified virus is applied as a coating onto the microtiter plate (2), or antibody-capture methods, where the plates are coated with anti-human IgG (6). Both of these approaches have disadvantages associated with them. The use of purified live virus is undesirable, both from a safety standpoint and because the preparation of multiple purified viruses is impractical. The antibody-capture method employs inactivated viral antigen and is therefore convenient; however, the anti-human IgG captures all IgG present in the sera. IgG persists long after an infection, and therefore this method is likely to suffer from a lack of sensitivity due to competition from nonspecific IgG. Barry et al. (1) ...
Authors: Bobrowska-Korczak, Barbara , Skrajnowska, Dorota , Tokarz, Andrzej Article Type: Research Article Abstract: Backround: Epigenetic alterations have been identified as promising new targets for cancer prevention strategies as they occur early during carcinogenesis and represent potentially initiating events for cancer development. Objective: The aim of the present study was to assess the effect of zinc and copper on the DNA methylation in rats whose breast adenocarcinoma was simultaneously induced with 7, 12 dimethylbenz[a]anthracene (DMBA). The reseach focused on the kinetics of alterations in urinary 5-MedC (5-methyl-2-deoxycytidine) at the early and late stages of carcinogenesis, as well as the influence of dietary factors on the process. Methods: The content of …5-methyl-2-deoxycytidine in the rats urine was determined by the ELISA (enzyme-linked immunosorbent assay) method. The 5-MedC level was standardized by conversion to the creatinine level. Results: It was found that in the ...
In the present study, the Hyplex BloodScreen PCR-ELISA system was evaluated for the first time for direct identification of pathogenic bacteria in a large panel of positive BACTEC 9240 blood culture bottles. This test system allows identification of the bacteria within ca. 4.5 to 6 h, including DNA isolation, PCR amplification, and detection by reverse hybridization. Therefore, in contrast to conventional culture and biochemical identification techniques, which usually take 1 to 2 days, the Hyplex BloodScreen PCR-ELISA system generates results much quicker.. Concerning pure cultures of bacteria, the Hyplex BloodScreen PCR-ELISA system had a very high sensitivity, ranging from 96.6 to 100% for the various test modules (Table 1 and 2). The specificities of the different modules were also high and exceeded 97.5% in all assays but one. The test module for the detection of E. coli cross-reacted with B. fragilis, M. morganii, and one isolate of E. cloacae and therefore had a specificity of only 92.5%. ...
In countries with a high NPC incidence, such as Indonesia, screening for early-stage disease is very important, since most patients currently come to the hospital at stage III or IV, with the consequences of therapy failure and a low survival rate posing considerable health care problems. Detection of EBV-related serological abnormalities, such as elevated EBV IgA levels, may provide a timely diagnosis of protracted early-stage NPC, as revealed in recent studies (2, 15). The availability of affordable yet accurate serological tests, which can be automated for large-scale applications, will be of benefit to cancer screening programs in developing countries. The IgA ELISA using defined and distinct EBV antigen may fulfill the criteria for such a screening approach, in particular when combined with simple sampling, such as dried blood collection, as shown by us recently (9). In that study, sera from well-defined groups of NPC patients and regional healthy individuals were used to evaluate the ...
Hyaluronan (HA) is widely detected in biological samples and its concentration is most commonly determined by the use of a labeled specific HA binding protein (aggrecan G1-IGD-G2, HABP), employing membrane blotting and sandwich enzyme-linked immunosorbent assay (ELISA)-like methods. However, the detected signal intensity or the quantified value obtained by using these surface-based methods is related to the molecular mass (M) of HA, especially for HA in the low M range below ~150 kDa. At the same mass or mass concentration, higher M HA gives a higher signal than lower M HA. We have experimentally determined the quantitative relationship between the M of HA (in the range 20-150 kDa) and the relative signal intensity in comparison with a standard HA, in a sandwich ELISA-like assay. An M-dependent signal correction factor (SCF) was calculated and used to correct the signal intensity, so that the corrected concentration value would more accurately reflect the true HA concentration in solution. The ...

Mouse hepatitis virus (MHV) is a major pathogen in laboratory mice that usually leads to fatal diseases, such as hepatitis, multiple sclerosis, encephalitis, and respiratory disease. MHV has a high infection rate, and it needs to be detected as soon as possible to prevent its spread to other facilities. However, MHV detection by enzyme-linked immunosorbent assay (ELISA) often gives false positives; thus, it is very important that the results are confirmed as true positives in the early infection stage or distinguished as false positives with more accurate, reliable methods. Under microbiological screening, MHV ELISA-positive mice were found in four GFP-tagging transgenic mice. To verify the detection of the MHV antigen directly, reverse transcription polymerase chain reaction (RT-PCR) was performed, and the mice were determined to be MHV negative. Additional serum antibody-based screening was conducted with three different ELISA kits, and multiplexed fluorometric immunoassay (MFIA) was performed ...

The symptoms mentioned above are the mild symptoms for COVID-19, which begins mild and gradually develops into something severe. Some recover from these symptoms without hospitalization. However, others become critically ill and have difficulty in breathing.. The most vulnerable people who can contract the disease are the elderly and people who have underlying medical problems. These medical problems include heart problems, lung problems, diabetes, and cancer. However, those with mild symptoms can transmit the disease to other people.. Coronavirus COVID-19 IgM ELISA Assay Kit. The enzyme-linked immunosorbent assay (ELISA) is a biochemistry assay that detects proteins, peptides, hormones, and antigens from test samples.

Background Chlamydia trachomatis (CT) DNA testing of genital samples principally from symptomatic persons provides information about active infection only, and is unlikely to represent true prevalence of current and past infection in the population. Serological tests applied to serum collections that are more representative of the general population can help understanding the pattern of the infection. We previously described an indirect immunoglobulin G (IgG) enzyme-linked immunosorbent assay (ELISA) based on the CT-specific antigen Pgp3. Sensitivity and specificity were determined using ROC curve analysis of data from 356 sera from CT-infected patients and 722 paediatric sera. The assay works particularly well in women, with a greater sensitivity (74%) than commercial assays (60%), and is suitable for use in seroprevalence studies. However, there is a need to confirm the specificity of samples reactive in the indirect Pgp3 ELISA and, to this end, we have developed a competitive Pgp3 ...
Sterigmatocystin (STG), a biosynthesis precursor of aflatoxin B1, is well known for its toxic and carcinogenic effects in humans and animals. STG derivatives and protein conjugates are needed for generation of monoclonal antibodies (mAbs). This work describes a reliable and fast synthesis of novel STG derivatives, based on which novel STG bovine serum albumin conjugates were prepared. With the novel STG bovine serum albumin conjugates, three sensitive and specific mAbs against STG, named VerA 3, VerA 4, and VerA 6, were prepared by semi-solid hypoxanthine/aminopterin/thymidine (HAT) medium using a modified two-step screening procedure. They exhibited high affinity for STG and no cross-reactivity (CR) with aflatoxins B1, B2, G1, G2, and M1. Based on the most sensitive antibody VerA 3, an ultra-sensitive competitive enzyme-linked immunosorbent assay (ELISA) was developed for STG in wheat, maize, and peanuts. Assays were performed in the STG-GA-BSA-coated (0.5 g mL(-1)) ELISA format, in which the ...
A partially purified 125I-labeled antibody directed against the murine major histocompatibility complex and injected i.v. pregnant females is selectively absorbed by the placenta when the fetus bears the appropriate targen antigen. The placenta specifically absorbs the antibody at both 13 days and 17 days of gestation, and the differential uptake is found as early as 2 hr after injection and as late as 12 hr. It is also seen in 13-day placentas that have had the fetus removed surgically, indicating that fetal circulation is not essential for the absorption to take place. Specificity controls eliminate the possibility that the differential uptake is due to Fc receptor binding or undefined effects of hybrid vigor. This increase in binding is not seen in the livers, spleens, kidneys, or lungs of the pregnant females. There is a slight decrease in radioactivity in the serum. These results indicate that the placenta is a paternal antigen-bearing immunoabsorbent that could serve as a barrier

Generally, testing kits operate based on detection of antibodies (by enzyme-linked immunosorbent assay, or enzyme-linked immunosorbent assay (ELISA)) or RNA (by polymerase chain reaction, or PCR) associated with the virus (from nasopharyngeal swabs taken from individuals noses and throats). This relies on their surface interactions with a complementary detection ligand or strand in the kit18. However, these testing kits are generally associated with problems such as false-negative results, long response times and poor analytical sensitivity19. To this end, due to their extremely large surface-to-volume ratios, nanosized materials can instigate highly efficient surface interactions between the sensor and the analyte, allowing faster and more reliable detection of the virus20. Accordingly, a group of researchers have developed a colloidal gold-based test kit that enables easy conjugation of gold nanoparticles to IgM/IgG antibodies in human serum, plasma and whole blood samples21. However, the ...
