Prevalence of anti-HBc in HBsAg negative blood donors using two enzyme immunoassays kits
Abstract Background and Objectives Use of kits with high sensitivity and specificity to determine the prevalence of antibodies against hepatitis B virus (anti-HBc) core antigen is important. The aim of this study was to determine the prevalence of hepatitis B virus antibody in HBsAg negative blood donors using two anti-HBc enzyme immunoassay kits (DIA.PRO and SIEMENS). Materials and Methods...
متن کاملIndication of Anti-HBc Antibody Screening and HBV-DNA Detection in Diagnosing Latent Hepatitis B Virus Infection
Background: In spite of available, and sensitive screening assay for detection of hepatitis B virus surface antigen (HBsAg), occasional cases of post-transfusion hepatitis B virus infection are still observed. The aim of the present study was to assess the prevalence of positive anti hepatitis B core (anti-HBc) and presence of HBV-DNA in serum sample of healthy blood donors negative for both HB...
متن کاملUsing Boehmite Nanoparticles as an Undercoat, and Riboflavin as a Redox Probe for Immunosensor Designing: Ultrasensitive Detection of Hepatitis C Virus Core Antigen
In this study a label-free electrochemical Immunosensor for ultrasensitive detection of Hepatitis C virus core antigen in serum samples was fabricated by using a simple approach. In this method a low-cost and sensitive immunosensor was fabricated based on a boehmite nanoparticles (BNPs) modified glassy carbon. The BNPs provide a specific platform with increased surface area which is capable of ...
متن کاملSignificance of Hepatitis B Core Antibody as the Only Marker of Hepatitis B Virus Infection in High Risk Patients
Background and Objective: Presence of hepatitis B core antibody (anti-HBc) in the absence of hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) is defined, as isolated anti-HBc. little is known about the clinical significance of the isolated anti-HBc in hepatitis B virus (HBV) infections. The aim of this study was to assess the significance of anti-HBc as the onl...

Two antigen-antibody systems were Out of 42 sera from patients with acute viral hepatitis 33 were positive for HBsAg,all HBsAg positive individuals possessed anti-HBc. From 11 blood donors sera 8 were positive for HBsAg and 9 were Positive for anti-HBc;2 leprosy sera were tested,both of them were positive for HBsAg and anti-HBc. 5 miscellaneous samples,z·were positive for HBsAg and anti-HBc...
متن کاملExpression of Hepatitis B Virus Core Antigen in Native and Fusion Forms in E. coli
DNA coding for the core antigen from hepatitis B Virus (HBcAg) was amplified, cloned and propagated in E. coli. The core protein was expressed in E. coli and the product was readily detected by Western blot. This protein can be used as a diagnostic material in serum screening tests. To increase the level of expression of this antigen in bacteria, two plasmids were constructed in which the gene ...
