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 ...

Univariate and multivariate analysis were performed to identify the risk factors associated with HSV ...
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
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). The concept behind this application is that the binding degree of inclusion bodies from lysed fermentation broth to the cryogel minicolumns increases with an increase in their concentration during fermentation. The technique allowed us to monitor the increase in the production levels of the ...

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%. ...
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 ...

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

Background. We report the first-in-human safety and immunogenicity assessment of a prototype Ad26 vector-based human immunodeficiency virus (HIV) vaccine in humans. Methods. Sixty Ad26-seronegative, healthy, HIV-uninfected subjects were enrolled in a randomized, double-blinded, placebo-controlled, dose-escalation phase 1 study. Five groups of 12 subjects received 10(9)-10(11) vp of the Ad26-EnvA vaccine (N = 10/group) or placebo (N = 2/group) at weeks 0 and 24 or weeks 0, 4, and 24. Safety and immunogenicity were assessed. Results. Self-limited reactogenicity was observed after the initial immunization at the highest (10(11) vp) dose. No product-related SAEs were observed. All subjects who received the Ad26-EnvA vaccine developed Ad26 NAb titers, EnvA-specific enzyme-linked immunosorbent assays (ELISA) titers, and EnvA-specific enzyme-linked immunospot assays (ELISPOT) responses. These responses persisted at week 52. At week 28 in the 10(9), 10(10), 10(11) vp 3-dose and the 10(10) and 5 × ...
In an attempt to gain more knowledge about the immunogenicity of the variable domains (VDs) of the major outer membrane protein (MOMP) of Chlamydia pneumoniae, peptides representing these areas were used to immunize BALB/c and C57BL/6 mice. Antisera to the peptides and to peptides conjugated to keyhole limpet hemocyanin (KLH) were characterized by their ability to recognize the immunizing peptide and elementary bodies (EBs) of C. pneumoniae by enzyme-linked immunosorbent assay (ELISA) and Western blot (immunoblot). In addition, antiserum was analyzed for its molecular specificity by a pepscan as well as its in vitro neutralizing ability. In general, results obtained with antisera to the peptides paralleled the results obtained with the antisera to the KLH-conjugated peptides except that the titers or strength of reaction in the assays was less. Antisera to the VDs in both strains of mice gave ELISA titers to the homologous VD peptide ranging from 1,000 to ,64,000. The strength of reactivity with ...

Adequately sensitive and specific methods to diagnose pertussis in adolescents and adults are not widely available. Currently, no Food and Drug Administration approved diagnostic assays are available for the serodiagnosis of Bordetella pertussis. Since concentrations of B. pertussis-specific antibodies tend to be high during the later-phases of disease, a simple, rapid, easily transferable serodiagnostic test was developed. This paper describes test development, initial evaluation of a prototype kit enzyme-linked immunosorbent assay (ELISA) in an inter-laboratory collaborative study, and the analytical validation. The data presented here demonstrate that the kit met all pre-specified criteria for precision, linearity, and accuracy for samples with anti-pertussis toxin (PT) immunoglobulin G (IgG) antibody concentrations in the range of 50 to 150 ELISA units (EU)/mL, the range believed to be most relevant for serodiagnosis. The assay met the precision and linearity criteria for a wider range, ...

In this thesis, the development of an immunoassay system for glycosylated albumin is described. The technique that was used consisted of affinity separation of glycosylated from non-glycosylated albumin, followed by an enzyme-linked immunosorbent assay (ELISA) for albumin. The assay sensitivity was 2mg/l and was sufficiently sensitive to measure the glycosylated albumin concentration in the urine and plasma of both diabetic and non-diabetic subjects. An overnight timed urine sample and blood sample were collected from 85 diabetic subjects (56 IDDM, 29 NIDDM) and 39 age and sex matched non-diabetic control subjects. Plasma and urinary glycosylated albumin, urinary alpha1-microglobulin, glycosylated haemoglobin, plasma and urinary creatinine were measured. Duration of diabetes, body weight and presence of retinopathy were noted. The diabetic subjects were grouped according to their albumin excretion rate (AER) and a relationship was found between urinary glycosylated albumin and albumin excretion ...
The different expression level of Dickkopf-1 (DKK-1) in different cancers shows that the function of DKK-1 depends on the histological type of the cancer cells and the tissue microenvironment. To our knowledge, the serum expression level of DKK-1 in breast cancer is little known. Blood samples from 125 consecutive patients diagnosed with breast cancer and 53 control subjects from March 2008 to August 2013 were investigated. Serum DKK-1 expression levels were measured by enzyme-linked immunosorbent assay (ELISA). The overall survival (OS) and relapse-free survival (RFS) analyzed by log-rank test, and survival curves were plotted according to Kaplan-Meier. The mean serum level of DKK-1 in patients with breast cancer was 4.99 ± 1.50 ng/mL, and was significantly higher than that in healthy individuals (1.88 ± 0.81 ng/mL, P | 0.001). DKK-1 level correlated significantly with TNM stage (P = 0.009), tumor grade (P = 0.02), lymph node metastasis (P = 0.001), and expression of HER2 (P = 0.002). The DKK-1
Human papillomavirus high risk (HPV-HR) type 16 is a significant risk factor for head and neck cancers (HNC) independent of tobacco and alcohol. The purpose of this study was to determine whether antibody levels to the HPV-16 oncoproteins E6 and E7 measured in sera collected at baseline (BL) prior to treatment and at two post-treatment follow-up (FU) visits were associated with HNC risk factors or prognosis. Presence of antibodies to HPV-16 E6 and E7 was evaluated in 109 newly diagnosed HNC cases with BL and FU blood samples, using the enzyme-linked immunosorbent assay (ELISA). HPV-16 E6 and/or E7 seropositive HNC cases were associated with higher risk in younger patients (≤ 55 years), more sexual partners (≥ 10), oropharyngeal cancer, worse stage at diagnosis, poorer grade, and nodal involvement. Between BL and FU (median = 8.3 months), there were decreased antibody levels for seropositive E6 (73% vs. 27%, p = 0.02) and seropositive E7 patients (65% vs. 35%, p = 0.09) with 5% of BL E6 and 35% of BL
The MP DIAGNOSTICS (MPD) HIV Ag/Ab Combo ELISA 4.0 is an enzyme-linked immunosorbent assay (ELISA) intended for qualitative detection of antigens and/or antibodies to Human Immunodeficiency Viruses (HIV) type 1 (group M - O) and/or type 2 in human serum or plasma samples.
Despite the wealth of commercially available antibodies to human proteins, research is often hindered by their inconsistent validation, their poor performance and the inadequate coverage of the proteome. These issues could be addressed by systematic, genome-wide efforts to generate and validate renewable protein binders. We report a multicenter study to assess the potential of hybridoma and phage-display technologies in a coordinated large-scale antibody generation and validation effort. We produced over 1,000 antibodies targeting 20 SH2 domain proteins and evaluated them for potency and specificity by enzyme-linked immunosorbent assay (ELISA), protein microarray and surface plasmon resonance (SPR). We also tested selected antibodies in immunoprecipitation, immunoblotting and immunofluorescence assays. Our results show that high-affinity, high-specificity renewable antibodies generated by different technologies can be produced quickly and efficiently. We believe that this work serves as a ...

Evidence-based recommendations on enzyme-linked immunosorbent assay (ELISA) tests for therapeutic monitoring of TNF-alpha inhibitors in rheumatoid arthritis
The analysis of human serum for different biomarkers holds promise for the early detection, diagnosis and treatment of a variety of diseases, such as cystic fibrosis, arthritis and multiple types of cancer. Serum biomarkers can be used as indicators of the state of disease progression or simply as indicators for the functioning of normal biological processes within the human body. Ultimately, these biomarkers can monitor the progress of therapy [1,2]. For routine analysis of only one or a few analytes, the enzyme-linked immunosorbent assay (ELISA) remains the workhorse method for protein analysis in basic research and clinical diagnostics. Owing to increasing efforts in recent years in biomarker discovery [3,4], many high-quality antibodies with high specificity and affinity are becoming available to these markers and to entire proteomes [5-8] for basic research, early detection of cancer and other medical diagnostics [9,10].. Mass spectrometry has emerged as a powerful tool for comprehensive ...

BACKGROUND: Guang-Pheretima, which is originated from Pheretima aspergillum, has been documented in academic Chinese herbal studies for nearly 2000 years for its prominent treating effects of various inflammatory diseases such as asthma, cough and fever. However, the anti-inflammatory activity and mechanism of Guang-Pheretima has been rarely reported. Hence, we investigated the inhibitory effect and the underlying mechanism of Guang-Pheretima aqueous extracts on inflammatory response in RAW 264.7 cells. METHOD: RAW 264.7 macrophages were pretreated with various concentrations of Guang-Pheretima decoction (GPD) or protein-free Guang-Pheretima decoction (PF-GPD) and subsequently stimulated with lipopolysaccharide (LPS) to trigger the inflammatory response. Productions of nitric oxide (NO) were determined by Griess reaction, and prostaglandin E (PGE ), tumor necrosis factor-α (TNF-α), interleukin (IL)-1 , IL-6 were measured by enzyme-linked immunosorbent assays (ELISA).

Serological response of animals vaccinated against PRRSV can differ between individuals. Some pigs may not show any response, or very low level of ELISA antibodies. Positive results of ELISA prove contact of a population with PRRSV (wild type or modified live vaccine). The larger the number of pigs tested, the more accurate is the diagnosis. PRRS ELISA can detect antibodies starting from 10-14 days after the contact with the virus. Some pigs can seroconvert later than others. ELISA results are very difficult to interpret in individual pigs. The antibodies detected in ELISA are usually targeted against nucleocapsid protein. These antibodies play no role in immunity against PRRSV. There are no commercially available ELISA kits (or experimental ones) to verify the level of immunity. Pigs negative in ELISA can still be immune. Vaccines against PRRS usually dont protect pigs against infection for entire life. They are intended to limit virus shedding and clinical signs after infection. Vaccines may ...

Two enzyme-linked immunosorbent assays (ELISA) for the determination of homidium in serum of treated cattle have been developed and evaluated. One is a direct competition (Assay 1) and the other an indirect competition assay (Assay 2). Both assays are highly sensitive with a limit of detection of 0.1 ng homidium per mL serum. Homidium levels were measurable in serum of cattle for over 2 months following administration of a single intramuscular (i.m.) dose at 1 mg/kg bodyweight. The level of sensitivity afforded by these assays makes them potentially useful tools in the pharmacokinetic evaluation of homidium and for invetigating drug resistance or causes of drug failure. Assay 2 was chosen as being most suitable for further studies ...

Mouse IL-2 total antigen assay ELISA kit - induces proliferation of various lymphocytes including CD4+ and CD8+ T cells, natural killer cells, and B cells
Enzyme-linked immunosorbent assay (ELISA) is a sensitive, heterogenous (multiple phase) analytical technique for quantitation of antigen or antibody in which enzyme-labeled antibody or antigen is bound to a solid support (e.g., tubes, beads, microtiter plate wells, plastic tines or fins). After addition of patient specimen and substrate, antigen, antibody or complex are detected by a color change indicating the presence of the product of an enzyme-substrate reaction. Direct ELISA is a technique for measuring antigen using competition for antibody binding sites between enzyme- labeled antigen and patient antigen. Indirect ELISA, or enzyme immunometric assay, measures antibody concentrations using bound antigen to interact with specimen antibodies. Enzyme-labeled reagent antibodies can be isotype-specific (i.e., capable of determining the presence of IgG, IgA, IgM or IgE classes which react with the antigen of interest). The specificity of indirect ELISA assays for IgM isotypes in some infectious ...

Public Policy Statement on HIV Testing of Patients in Addiction Treatment Facilities. PDF. Background. Technology is currently available to assess the presence of HIV antibodies as well as to detect the presence of viral particles (antigens) in the human blood stream. The primary method for testing for antibodies is the ELISA test. Samples that react to the ELISA test are then tested with a more sophisticated blood test called the Western Blot, which confirms the presence of antibodies to HIV. There is a substantial incidence of false positive ELISA tests; therefore it is essential to confirm any positive ELISA with a Western Blot test. HIV antibodies usually appear within six (6) weeks of infection and are most always present by six (6) months post infection.. Antigens usually appear within a few weeks of infection and disappear within a few months. Later, if the virus is activated, the dormancy ends and the antigen level rises. A rising antigen level is typically associated with deterioration ...
