Immunological comparison of the proteins of chicken and rat liver ribosomes. (1/4669)

A comparison of the proteins of chicken and rat liver ribosomes using immunochemical techniques was undertaken. The procedures included quantitative precipitation, passive hemagglutination, and immunodiffusion on Ouchterlony plates. The results indicate that antisera specific for chicken or rat liver ribosomes recognize only about 20% of common determinants. While there are important reservations, the results suggest extensive differences in the proteins of rat and chicken liver ribosomes. Despite those differences, rat and chicken liver ribosomal proteins maintain some homologous sequences present in bacterial ribosomal proteins. An enriched antibody preparation against chicken 80 S ribosomes inhibited the poly(U)-directed synthesis of polyphenylalanine and the elongation factor G (EF-G)-catalyzed binding of [3H]GDP to Escherichia coli ribosomes. Thus, chicken liver ribosomes, like ribosomes from rat liver and yeast, must have proteins homologous with those of E. coli ribosomes.  (+info)

Performance and specificity of monoclonal immunoassays for cyclosporine monitoring: how specific is specific? (2/4669)

BACKGROUND: Immunoassays designed for the selective measurement of cyclosporin A (CsA) inadvertently show cross-reactivity for CsA metabolites. The extent and clinical significance of the resulting overestimation is controversial. A comprehensive assessment of old and new methods in clinical specimens is needed. METHODS: In a comprehensive evaluation, CsA was analyzed in 145 samples with the new CEDIA assay and compared with the Emit assay with the old and new pretreatments, the TDx monoclonal and polyclonal assays, the AxSYM, and HPLC. All samples were from patients with liver and/or kidney transplants. RESULTS: The CEDIA offered the easiest handling, followed by the AxSYM, which showed the longest calibration stability. The TDx monoclonal assay provided the lowest detection limit and the lowest CVs. The mean differences compared with HPLC were as follows: Emit, 9-12%; CEDIA, 18%; AxSYM, 29%; and TDx monoclonal, 57%. The CycloTrac RIA paralleled the Emit results. In contrast to the mean differences, substantial (>200%) and variable overestimations of the CsA concentration were observed in individual patient samples. Metabolic ratios, estimates of the overall concentrations of several cross-reacting metabolites (nonspecific TDx polyclonal/specific reference method), correlated with the apparent biases of the various monoclonal assays. Metabolic ratios varied up to 10-fold, which translated into biases for individual samples between -7% and +174%. The higher the cross-reactivity of an assay was, the higher was the range of biases observed. The interindividual differences markedly exceeded other factors of influence (organ transplanted, hepatic function). CONCLUSION: Because assay bias cannot be predicted in individual samples, substantially erratic CsA dosing can result. The specificity of CsA assays for parent CsA remains a major concern.  (+info)

Automated homogeneous immunoassay for gentamicin on the dimension clinical chemistry system. (3/4669)

BACKGROUND: Monitoring of the concentration of gentamicin in serum and plasma during therapy is widely recommended and practiced in hospitals. Our aim was to develop a homogeneous immunoassay based on particle-enhanced turbidimetric inhibition immunoassay technology to quantify gentamicin on the Dimension clinical chemistry system. METHODS: Assay performance was assessed on each of the Dimension models in a 15-instrument interlaboratory comparison study. A split-sample comparison (n = 1171) was also performed between the gentamicin methods on the Dimension system and the Abbott TDx analyzer, using multiple reagent and calibrator lots on multiple instruments. RESULTS: The Dimension method was linear to 25.1 micromol/L (12.0 microg/mL) with a detection limit of 0.63 micromol/L (0.3 microg/mL). Calibration was stable for 30 days. The within-run imprecision (CV) was <1.3%, and total imprecision ranged from 1.8% to 3.2% between 4.2 micromol/L (2.0 microg/mL) and 16.7 micromol/L (8.0 microg/mL) gentamicin. Linear regression analysis of the results on the Dimension method (DM) vs the Abbott TDx yielded the following equation: DM = 0.98TDx - 0.42; r = 0.987. Minimal interference was observed from structurally related compounds such as sagamicin, netilmicin, and sisomicin. CONCLUSION: The monoclonal antibody used in this method has similar reactivities toward the individual gentamicin subspecies C1, C1a, and C2, thus providing analytical recovery not significantly dependent on relative subspecies concentrations.  (+info)

Serum IGF-binding protein-6 and prostate specific antigen in breast cancer. (4/4669)

OBJECTIVE: Recent studies have demonstrated the presence of the IGF-binding proteins (IGFBPs) and prostate specific antigen (PSA), an IGFBP protease. in human breast tissue. We sought to investigate the differences in serum IGFs, IGFBP-1, -3 and -6, and PSA between patients with surgically proven breast cancer and patients with benign breast disease. DESIGN AND METHODS: Concentrations of IGFs, IGFBP-1, -3 and -6, and PSA were determined in the sera from 57 patients with breast cancer (CA), and 46 women with benign breast disease (BBD) using immunoassays for IGFs and IGFBPs and an ultrasensitive ELISA for PSA. RESULTS: The mean (+/- S.E.M.) serum IGFBP-6 level in the CA group, 127 (16) ng/ml, was statistically significantly lower than in the BBD group, 157 (10) ng/ml (P = 0.016). Patients with CA had an elevated geometric mean serum PSA level of 0.018 (range: 0.0015-0.107) ng/ml, compared with 0.007 (range: 0.0015-0.019) ng/ml in women with BBD (P = 0.025). Mean serum IGFBP-1 concentrations were significantly lower in the CA group, 16 (2) ng/ml, versus 37 (4) ng/ml in the BBD group (P = 0.001). Mean serum IGFBP-3 concentrations were also lower in the CA group versus the BBD group, at 1981 (65) ng/ml, versus 2603 (140) ng/ml (P = 0.002) respectively. In the CA group, statistically significant correlations between PSA and IGFBP-6 (r = 0.413; P = 0.001), and between PSA and IGFBP-1 (r = -0.329; P = 0.021) were seen. Differences in IGF-I and -II between the two groups were not statistically significant. CONCLUSION: Lower serum concentrations of IGFBP-6, -3 and -1, but higher PSA concentrations were seen in the breast cancer group, and collectively these would suggest that there is an increase in bioavailable IGF-I in breast cancer.  (+info)

Differential immunodiagnosis between cystic hydatid disease and other cross-reactive pathologies. (5/4669)

We assessed an Echinococcus granulosus hydatid fluid antigen-ELISA (EgHF-ELISA) as a serologic prescreening test for E. granulosus infections, supplemented by more specific confirmatory tests, including arc-5 immunoprecipitation and antigen B subunit 8-kD immunoblotting. The diagnostic sensitivity of the EgHF-ELISA was 91%. With regard to the test specificity of the EgHF-ELISA (overall = 82%), we observed relatively frequent cross-reactions in tumor patients (6%) and in patients with other parasitic diseases. Cestode-related cross-reactivity can be resolved by the complementary use of E. multilocularis-specific antigens or Taenia solium cysticercosis-specific immunoblotting. Immunoblotting based upon the detection of antibody reactivity to the 8-kD antigen of EgHF, or if appropriately detectable, to the 29-kD and 34-kD bands exhibited a 91% diagnostic sensitivity and an overall specificity of 97% or 94%, respectively. Thus, immunoblotting provided a 99% discrimination between seropositive pre-operative cystic hydatid disease cases and cross-reactive non-cestode parasitic infections or malignancies.  (+info)

An immunoluminometric assay for N-terminal pro-brain natriuretic peptide: development of a test for left ventricular dysfunction. (6/4669)

Measurement of plasma levels of brain natriuretic peptide (BNP) has been used to assess left ventricular dysfunction and prognosis. Levels of the N-terminus of the precursor of BNP (NT-proBNP) have been reported to be elevated to a greater extent than BNP in left ventricular dysfunction. We have devised a non-radioactive sensitive and specific assay for NT-proBNP based on a competitive ligand binding principle. The chemiluminescent label 4-(2-succinimidyloxycarbonylethyl)phenyl-10-methylacridinium 9-carboxylate fluorosulphonate was used to label peptides representing domains in the middle and C-terminal sections of NT-proBNP. Assay of the C-terminal section of NT-proBNP (amino acids 65-76) in patients with proven left ventricular dysfunction [left ventricular wall motion index median 0.9 (range 0.3-1.4)] revealed elevated values [median 639 (386-911) fmol/ml] compared with normal controls [left ventricular wall motion index of 2 in all, NT-proBNP median 159 (120-245) fmol/ml, P<0.001]. Measurement of the middle section of NT-proBNP (amino acids 37-49) was not a discriminating test. It is thus possible to derivatize small peptides with a methyl acridinium label and preserve immunodetection with specific antibodies. Such methodology may allow non-radioactive immunoluminometric assays to be devised.  (+info)

Endometrial evaluation is not predictive for in vitro fertilization treatment. (7/4669)

PURPOSE: The main purpose of this study was to evaluate ovarian function by clomiphene citrate (CC) challenge test in a group of tubal infertile women and to study endometrial morphological maturation in the early luteal phase of CC-stimulated cycles as compared to in vitro fertilization (IVF) treatment outcome. METHODS AND RESULTS: Four women presented with strongly retarded, proliferative endometrium in the luteal phase. Of these, three presented with impaired ovarian function, high basal follicle-stimulating hormone, and high follicle-stimulating hormone levels after clomiphene stimulation on cycle day 10. In the remaining 30 women, showing an in-phase endometrium after CC stimulation, a comparison of six morphological characteristics did not reveal any significant differences between the 14 women who did become pregnant and the 16 who did not. No significant differences in endometrial thickness were observed between the groups. Significant differences were found when comparing estradiol and progesterone area under the curve during the luteal phase (P < 0.001 and P < 0.01, respectively) between those who did and those who did not become pregnant. CONCLUSIONS: Luteal endometrium morphology was not a sharp instrument to detect differences between women who did and women who did not become pregnant following IVF treatment, while ovarian function, as measured by hormonal markers, seemed to be a more reliable prognostic factor for IVF treatment outcome.  (+info)

Malignant transformation of human prostatic epithelium is associated with the loss of androgen receptor immunoreactivity in the surrounding stroma. (8/4669)

The cellular pathways involved in the pathogenesis of hormone resistance remain unclear. Studies evaluating the role of changes in human androgen receptor (hAR) expression in the progression of prostatic tumors have been inconclusive. Androgenic influence over prostatic growth is mediated via the regulation of interactions between stromal and epithelial cells. We hypothesized that neoplastic transformation of the prostate would be associated with alterations in hAR expression in the adjacent stroma. Using immunohistochemical techniques, we determined hAR positivity in the epithelium and adjacent stroma of sections from 17 benign and 39 malignant prostatic glands. We found that whereas the expression of the receptor decreased in both cellular compartments as the tissues dedifferentiated, the depletion was more pronounced in the stromal nuclei (P<0.0001). However, in sections from both untreated and hormone-resistant prostate cancer tissues, although heterogeneity of hAR expression in malignant epithelia was increased, there appeared to be a unique field effect around the cancerous prostate glands that resulted in a decreased expression of the receptor in the adjacent benign glands and its total loss in the surrounding stroma. The loss of hAR in the stroma adjacent to malignant prostatic epithelium may play an important role in prostate cancer progression. Furthermore, the similarity of the lack of stromal hAR expression in newly diagnosed and hormone-resistant prostate cancer (P = 0.85) may be an indication that the mechanisms responsible for the acquisition of hormone independence are established early in the malignant transformation process.  (+info)

Lateral Flow ImmunoassayLateral Flow Immunoassay
i-colloid 40 nm gold nanoparticles produced by IMRAs pulsed-laser ablation process are stabilized without surfactants or capping agents such as citrate, and conjugates for lateral flow immunoassays can be generated by high-efficiency passive adsorption of antibodies to particle surfaces. The tightly controlled laser-ablation process generates gold colloids that produce consistent lateral flow assay results. Pulsed-laser ablation also enables production of gold-alloy nanoparticles, such as gold-platinum, that can be passively conjugated like gold but have optical signatures distinct from gold due to their shifted surface plasmon resonance. Multicolor, multiplexed lateral flow immunoassays can be performed with combinations of gold and gold-alloy nanoparticles.. ...

Quantitative lateral flow immunoassay for total prostate specific antigen in serum / I. P. Andreeva, V. G. Grigorenko, A. M. Egorov, A. P. Osipov // Analytical Letters. - 2016. - Vol. 49, no. 4. - P. 579-588. A simple method for the rapid determination of prostate-specific antigen (PSA) in serum is reported using a lateral flow immunoassay with gold nanoparticles as the label. The method uses the intensity of colored test lines to determine PSA from 0.3 to 30 ng/ml. The limit of detection was 0.3 ng/ml and the coefficient of variation was less than 10%. The analysis time was approximately twenty minutes. The novel method showed good correlation with enzyme linked immunosorbent assay (ELISA) measurements of prostate-specific antigen concentration in human serum with a linear regression coefficient of 0.985. The developed system was stable for at least twelve months when stored from +4 to 30oC and has potential application for clinical practice. [ DOI ...

Procalcitonin (PCT) is a current, frequently-used marker for severe bacterial infection. The aim of this study was to develop a cost-effective detection kit for rapid quantitative and on-site detection of PCT. To develop the new PCT quantitative detecting kit, a double-antibody sandwich immunofluorescent assay was employed based on time-resolved immunofluorescent assay (TRFIA) combined with lateral flow immunoassay (LFIA). The performance of the new developed kit was evaluated in the aspects of linearity, precision, accuracy, and specificity. Two-hundred thirty-four serum samples were enrolled to carry out the comparison test. The new PCT quantitative detecting kit exhibited a higher sensitivity (0.08 ng/mL). The inter-assay coefficient of variation (CV) and the intra-assay CV were 5.4%-7.7% and 5.7%-13.4%, respectively. The recovery rates ranged from 93% to 105%. Furthermore, a high correlation (n = 234, r = 0.977, p | 0.0001) and consistency (Kappa = 0.875) were obtained when compared with the PCT kit

The role of nanoparticle design in determining analytical performance of lateral flow immunoassays - INBSThe role of nanoparticle design in determining analytical performance of lateral flow immunoassays - INBS
Rapid, simple, and cost-effective diagnostics are needed to improve healthcare at the point of care (POC). However, the most widely used POC diagnostic, the lateral flow immunoassay (LFA), is ∼1000-times less sensitive and has a smaller analytical range than laboratory tests, requiring a confirmatory test to establish truly negative results. Here, a rational and systematic strategy is used to design the LFA contrast label (i.e., gold nanoparticles) to improve the analytical sensitivity, analytical detection range, and antigen quantification of LFAs. Specifically, we discovered that the size (30, 60, or 100 nm) of the gold nanoparticles is a main contributor to the LFA analytical performance through both the degree of receptor interaction and the ultimate visual or thermal contrast signals. Using the optimal LFA design, we demonstrated the ability to improve the analytical sensitivity by 256-fold and expand the analytical detection range from 3 log10 to 6 log10 for diagnosing patients with ...

The diagnosis of periprosthetic joint infection (PJI) remains a challenge. However, recent studies showed that synovial fluid biomarkers have demonstrated greater diagnostic accuracy than the currently used PJI diagnostic tests. In many diagnostic tests, combining several biomarkers into panels is critical for improving diagnostic efficiency, enhancing the diagnostic precision for specific diseases, and reducing cost. In this study, we prove that combining alpha-defensin and C-reactive protein (CRP) as biomarkers possesses the potential to provide accurate PJI diagnosis. To further verify the result, we developed a multi-target lateral flow immunoassay strip (msLFIA) with staking pad design to obtain on-site rapid response for clinical diagnosis of PJI. A total of 10 synovial fluid samples were tested using the msLFIA, and the results showed that the combined measurements of synovial fluid alpha-defensin and CRP levels were consistent with those obtained from a commercial enzyme-linked immunosorbent

This study was conducted to develop a simple, rapid, and accurate lateral flow immunoassay (LFIA) detection method for point-of-care diagnosis. The one-dot LFIA for aflatoxin B1 (AFB1) was based on the modified competitive binding format using competition between AFB1 and colloidal gold-AFB1-BSA conjugate for antibody binding sites in the test zone. A Smartphone-based reading system consisting of a Samsung Galaxy S2 Smartphone, a LFIA reader, and a Smartphone application for the image acquisition and data analysis. The detection limit of one-dot LFIA for AFB1 is 5 μg/kg. This method provided semi-quantitative analysis of AFB1 samples in the range of 5 to 1,000 μg/kg. Using combination of the one-dot LFIA and the Smartphone-based reading system, it is possible to conduct a more fast and accurate point-of-care diagnosis.

The presence of harmful algal blooms (HABs) can result in the accumulation of phycotoxins in shellfish such as mussels, scallops and oysters. Depending on the toxins present, consumption of contaminated shellfish can lead to illness in humans including amnesic, diarrheic or paralytic shellfish poisoning (ASP, DSP or PSP respectively). There is currently a lack of suitable rapid screening tools to complement accepted reference methods for the detection of marine biotoxins. The aims of the thesis were to develop a range of simple and accurate lateral flow immunoassays (LFIA) for the rapid screening of phycotoxins from shellfish extracts, which could be performed either in a laboratory or in the field. As a result, three novel single-step LFIAs were developed and validated for the major regulated toxins responsible for ASP, DSP and PSP, respectively. One of the challenges was to ensure that the thresholds for test~ were based at concentrations relevant to regulations, whilst minimizing the risks of ...

Inferring nonlinear lateral flow immunoassay state-space models via an unscented Kalman filterInferring nonlinear lateral flow immunoassay state-space models via an unscented Kalman filter
This paper is concerned with the problem of learning structure of the lateral flow immunoassay (LFIA) devices via short but available time series of the experiment measurement. The model for the LFIA is considered as a nonlinear state-space model that includes equations describing both the biochemical reaction process of LFIA system and the observation output. Especially, the time-delays occurring among the biochemical reactions are considered in the established model. Furthermore, we utilize the unscented Kalman filter (UKF) algorithm to simultaneously identify not only the states but also the parameters of the improved state-space model by using short but high-dimensional experiment data in terms of images. It is shown via experiment results that the UKF approach is particularly suitable for modelling the LFIA devices. The identified model with time-delay is of great significance for the quantitative analysis of LFIA in both the accurate prediction of the dynamic process of the concentration

While lateral flow test formats can be utilized with whole blood and low sample volumes, their diagnostic characteristics are inferior to immunoassays based on chemiluminescence immunoassay (CLIA) or enzyme-linked immunosorbent assay (ELISA) technology. CLIAs and ELISAs can be automated to a high degree but commonly require larger serum or plasma volumes for sample processing. We addressed the suitability of EDTA-anticoagulated whole blood as an alternative sample material for antibody testing against SARS-CoV-2 by electro-CLIA (ECLIA; Roche, Rotkreuz, Switzerland) and ELISA (IgG and IgA; Euroimmun, Germany). Simultaneously drawn venous serum and EDTA-anticoagulated whole blood samples from 223 individuals were included. Correction of the whole blood results for hematocrit led to a good agreement with the serum results for weakly to moderately positive antibody signals. In receiver-operating characteristic curve analysis, all three assays displayed comparable diagnostic accuracy (area under the ...

Presence of anti-HCV antibodies indicates prior exposure to HCV infection. However, the assay may be negative early in acute HCV infection, in immunosuppressed individuals. Anti-HCV antibodies can be detected by rapid immunoassays, enzyme-linked immunosorbent assays (ELISA), or chemiluminescent immunoassays. Quality of some of the test kits for anti-HCV may be a reason for concern.. Rapid immunoassay tests use a unique combination of modified HCV antigens conserved across all genotypes. However, some studies have demonstrated that rapid tests cannot be solely relied upon in screening patients from high- risk population in India. ELISA tests indicate presence of antibodies against HCV core, NS3 and NS5 regions. A study in North India has demonstrated the value of blood banks screening using two ELISA kits concurrently to improve detection of contaminated blood.. Enhanced chemiluminescence immunoassay (ECi) a quantitative assay based on chemiluminescent reaction, which is as good as ELISA.. ...

Excellent retention of beads, even after extensive washing. According to a publication at Journal of Immunological Methods by Prof. Beaumier at Baylor and Dr. Biswas at Merck, the DA-Bead method for analysis was comparable to, if not superior to, the conventional method in terms of consistency/precision, accuracy, sensitivity and dynamic range.. It is known that bead-based assays sometimes suffer from bead aggregation with plasma, blood, and other challenging biological samples which affects detectability of proteins and jeopardizes quality of data. Scientific studies have shown that DropArray may reduce bead aggregation and may better permit reading beads individually reporting the signals of target proteins as they are.. ...

Successive Optimization of a Homogeneous Immunoassay for Antibody Detection in Viral Infections[v1] | PreprintsSuccessive Optimization of a Homogeneous Immunoassay for Antibody Detection in Viral Infections[v1] | Preprints
Although there are extensive literature reports on the use of gold nanoparticle (AuNP) based homogeneous assays for detection of biomolecules, very few experimental description and procedures involving their preparation are described. In this study, AuNPs conjugated to Bovine Serum Albumin or Envelope protein from Dengue II were developed as a homogeneous immunoassay for antibody detection. We report here optimization of key parameters to prepare an immunoassay like conjugation protein concentration, centrifugation time, electrolyte addition and assay temperature. We determined that saturating protein concentrations improved AuNPs surface coverage and uniformity of the assay and addition of sodium chloride improved sensitivity of the antibody detection method and assay stability. Furthermore, we showed that dynamic light scattering can be used to monitor changes in gold nanoparticles in the preparation and detection steps. Additionally, numerical simulations of the plasmonic optical response of AuNPs

Detection of sulphathiazole in honey samples using a lateral flow immunoassayDetection of sulphathiazole in honey samples using a lateral flow immunoassay
EN] A lateral flow immunoassay (LFIA) was developed in the competitive reaction format and applied to test sulphathiazole (STZ) residues in honey samples. To prepare the assay test, a hapten conjugate and goat antirabbit antiserum as capture and control reagent, respectively, were dispensed on nitrocellulose membrane. Polyclonal antiserum against sulphathiazole was conjugated to colloidal gold nanoparticles and used as the detection reagent. The visual limit of detection (cut-off value) of the sulphathiazole LFIA was 15 ng/g, reaching qualitative results within 10 min. The assay was evaluated with STZ spiked honey samples from different geographical origins (n = 25). The results were in good agreement with those obtained from liquid chromatography separation and mass spectroscopy detection (LC-MS), indicating that the LFIA test might be used as a qualitative method for the determination of sulphathiazole residues without expensive equipment. The test was also highly specific, showing no ...

Development of an 8-Plex Luminex Assay to Detect Swine Cytokines for V by Steven Lawson, Joan Lunney et al.Development of an 8-Plex Luminex Assay to Detect Swine Cytokines for V by Steven Lawson, Joan Lunney et al.
A Luminex (Luminex Corp., Austin, TX) multiplex swine cytokine assay was developed to measure 8 cytokines simultaneously in pig serum for use in assessment of vaccine candidates. The fluorescent microsphere immunoassay (FMIA) was tested on archived sera in a porcine reproductive and respiratory syndrome virus (PRRSV) vaccine/challenge study. This FMIA simultaneously detects innate (IL-1β, IL-8, IFN-α, TNF-α, IL-12), regulatory (IL-10), Th1 (IFN-γ) and Th2 (IL-4) cytokines. These proteins were measured to evaluate serum cytokine levels associated with vaccination strategies that provided for different levels of protective immunity against PRRSV. Pigs were vaccinated with a modified-live virus (MLV) vaccine and subsequently challenged with a non-identical PRRSV isolate (93% identity in the glycoprotein (GP5) gene). Protection (as defined by no serum viremia) was observed in the MLV vaccinated pigs after PRRSV challenge but not those vaccinated with killed virus vaccine with adjuvant (KV/ADJ) (99%

Studies towards automated ovulation prediction in the pig industry: an electrochemical immunosensor for oestradiol in saliva ...Studies towards automated ovulation prediction in the pig industry: an electrochemical immunosensor for oestradiol in saliva ...
Accurate ovulation prediction in pigs could lead to considerable reduction in losses incurred through failed artificial insemination, poorly controlled litter sizes and unnecessary culling of inaccurately diagnosed barren sows. The aim of this work is to predict the onset of oestrus in pigs by monitoring oestradiol levels in saliva. An automated method is proposed, for use outside the laboratory, based on single-use screen-printed electrochemical immunosensors. This approach follows on from previous work by the same authors towards an automated electrochemical progesterone monitor. This paper will describe the preparation of oestradiol sensors by immobilisation of monoclonal antibody onto the carbon electrode surface. Use of the sensors will be described in a competitive immunoassay format, where oestradiol (in buffer or saliva) competes against alkaline-phosphatase-labelled antigen for surface binding. Introduction of the enzyme substrate 1-naphthyl phosphate results in hydrolisis to produce ...

Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis are pathogens commonly associated with infectious diseases in childhood. This study aimed to develop a fluorescent multiplexed bead-based immunoassay (FMIA) using recombinant proteins for the quantitation of serum IgG antibodies against these bacteria. Eight pneumococcal proteins (Ply, CbpA, PspA1, PspA2, PcpA, PhtD, SP1732-3 and SP2216-1), 3 proteins of H. influenzae (NTHi Protein D, NTHi0371-1, NTHi0830), and 5 proteins of M. catarrhalis (MC Omp CD, MC_RH4_2506, MC_RH4_1701, MC_RH4_3729-1, MC_RH4_4730) were used to develop the FMIA. Optimal coupling concentrations for each protein, comparison of singleplex and multiplex assays, specificity, reproducibility, and correlation to ELISA for six pneumococcal antigens were determined for validation. FMIA was then used to analyze acute and convalescent paired serum samples of 50 children with non-severe pneumonia. The coupling concentrations varied for different antigens, ...

An improved sandwich immunoassay for Toxoplasma gondii antigens associated with acute forms of Toxoplasma infection is disclosed. The assay employs either an F(ab)2 fragment of IgG which reacts specifically with such antigens or a monoclonal antibody for such antigens as the substrate layer in the sandwich. The assay is sensitive and, unlike prior sandwich assays for the antigen, is not affected significantly by cross-reactions with rheumatoid factor.

Currently available enzyme immunoassay methods for peptides can be divided into two groups, homogeneous and heterogeneous methods. Homogeneous enzyme immunoassay methods, in which signals that are directly obtained from a mixture of test samples and reagents correlate with the amount of peptide in test samples, are simpler and quicker but less sensitive than heterogeneous enzyme immunoassay methods, in which free and bound forms of enzyme-labeled reactants are separated from each other.

New paper-based test can help in early detection of HIV | The Siasat DailyNew paper-based test can help in early detection of HIV | The Siasat Daily
The problem is particularly prominent in developing countries, where infectious diseases often go undetected for long periods of time, resulting in widespread epidemics.. Currently, cheap point-of-care methods employed to detect infectious diseases have their limitations, particularly when it comes to detecting very low levels of markers in the blood.. Now, Imperial researchers, alongside their collaborators at University College London, have developed a new diagnostic tool for HIV that is affordable, capable of withstanding harsh conditions and highly sensitive, making the early detection of the disease possible.. The research, published in the journal ACS Nano, refined a current diagnostic method known in the field as a lateral flow immunoassay, a similar method employed by pregnancy tests.. In the case of HIV, if a patient is positive, virus components present in the blood will bind to coloured particles on the paper test, indicating HIV infection.. To the best of our knowledge, our newly ...

Pyrimethanil is a widely used post-harvest fungicide whose residues are commonly found in fruits and vegetables. We herein report the synthesis of two new functionalized derivatives of pyrimethanil carrying an equivalent spacer arm at different positions of the molecule. The influence of the linker tethering site on the affinity of monoclonal antibodies was shown. Moreover, the development of competitive immunoassays in different formats and with high sensitivity to the target analyte - IC,inf,50,/inf, values below 0.3μg/L - is described. Optimized assays were characterized by the determination of the limit of quantification, trueness, and precision using water-diluted QuEChERS extracts of fruits and vegetables fortified with pyrimethanil. Finally, in-field treated and blind spiked strawberry, tomato, and cucumber samples were analyzed by the developed immunoassays and a reference chromatographic method. Using Deming regression analysis, we show that results from both methodologies were ...

Reveal® for Histamine | NEOGENReveal® for Histamine | NEOGEN
Reveal for Histamine is a single-step lateral flow assay based on a competitive immunoassay format. The extract is wicked through a reagent zone, which contains histamine-specific antibodies conjugated to coloured particles. If histamine is present, it will be captured by the particle-antibody complex. The histamine-antibody-particle complex then is wicked onto a membrane, which contains a zone of histamine conjugated to a protein carrier. This zone captures only uncomplexed antibody-particle conjugate, allowing the coloured particles to concentrate and form a visible line. The membrane also contains a control zone where the antibody-particle complex present in the reagent zone is captured by an antibody, forming a visible line. The control line will always form regardless of the presence of histamine, ensuring the strip is functioning properly. In addition, the control line also is used as a reference for comparison to the test zone for visual interpretation of the test results. If histamine is ...

Interpretation of hormone levels in older patients: points for consideration. (Sztefko and Szybowska 2012) Download. Blood hormone and tumor marker concentrations are usually determined by immunochemical methods which are based on an unique reaction between antigen and assay capture antibody. Despite the speed and simplicity of assays performance on automatic immunochemistry platforms, the interpretation of final results requires a deep knowledge of method fallibility. General lack of immunoassays standardization, presence of cross-reacting substances in patients sample, limitation of free hormones measurement due to abnormal analyte binding protein concentrations, assay interferences due to patients autoantibodies, and heterophilic antibodies, as well as proper interpretation of very low- and very high-sample analyte levels, are the main points discussed in respect to hormones and tumor markers measurement in geriatric population..

Vaccines in vitro characterization is required to identify optimal formulation conditions to ensure physical, chemical, and biological integrity of antigens and adjuvants. Analytical methods currently in use are mostly suitable for the characterization of unformulated antigens - requiring the complete desorption from aluminum-based adjuvants - and are not always able to reveal individual antigens in vaccine combinations. Here, the Luminex technology is proposed as proof of concept for the development of an improved analytical method for vaccine characterization, based on the use of specific antibodies bound to magnetic microspheres presenting unique digital signatures for simultaneous recognition of respective antigens in the entire formulation. TdaP combination vaccines were chosen as a model to develop an assay able to quantify acellular pertussis antigens and their levels of adsorption to adjuvant at the same time. This assay was directly applicable on the commercial vaccine product, avoiding ...
