Immunogenicity of peptide fusions to hepatitis B virus core antigen.
Several gene fusions have been constructed in which coding sequences for antigenic regions of the pre-S sequences of hepatitis B virus, hepatitis B surface antigen, and the envelope protein of human immunodeficiency virus were linked to the 3' end of that for the first 144 residues of hepatitis B core antigen. The sequences were expressed efficiently in Escherichia coli to give stable products ...
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 ...
متن کاملoccult hepatitis b virus infection among blood donors with antibodies to hepatitis b core antigen
diagnosis of hepatitis b is routinely based on of serological assay of hepatitis b surface antigen (hbsag). occult hepatitis b virus (hbv) infection is generally defined as the detection of hbv -dna in the serum or tissues of subjects who have negative test for hbsag. transmission of hbv infection has been documented from hbsag negative, anti-hbc positive blood and organ donors. the aim of this...
متن کاملLatent hepatitis B virus infection in healthy individuals with antibodies to hepatitis B core antigen.
Several recent reports have shown that hepatitis B virus (HBV) could be frequently transmitted to the recipients from donors who have antibodies to hepatitis B core antigen (anti-HBc) through liver transplantation. We provide here the molecular evidence of latent HBV infection accompanied with ongoing viral replication in the liver tissue of anti-HBc-positive healthy individuals. HBV DNA was de...
متن کاملOccult Hepatitis B Virus Infection among Blood Donors with Antibodies to Hepatitis B Core Antigen
Diagnosis of hepatitis B is routinely based on of serological assay of hepatitis B surface antigen (HBsAg). Occult hepatitis B virus (HBV) infection is generally defined as the detection of HBV -DNA in the serum or tissues of subjects who have negative test for HBsAg. Transmission of HBV infection has been documented from HBsAg negative, anti-HBc positive blood and organ donors. The aim of this...
