  • RelevanceHCV (Hepatitis C Virus) viral core protein forms the internal viral coat that encapsidates the genomic RNA and is enveloped in a host cell-derived lipid membrane. The hepatitis C virus (HCV) core protein represents the first 177 amino acids of the viral precursor polyprotein and is cotranslationally inserted into the membrane of the endoplasmic reticulum. The N terminus of the core protein is involved in transcriptional repression. There are over 20 different subtypes of Hepatitis C Virus; HCV type 1b is mostly found in Europe and Asia. The prevalence of HCV type 1b infection has recently decreased, although it still accounts for most HCV-related cirrhosis and hepatocellular carcinoma. High HCV viremia levels and HCV genotype type 1b are independent predictors for poor response to interferon-alpha therapy. HCV core protein is among the most conserved proteins in HCV and is known to induce sensitization of cytotoxic T lymphocytes (CTL). Therefore, it is a prime candidate for a component of a potential HCV vaccine.

    • ab2740 staining Hepatitis C Virus Core Antigen in the Huh7-Lunet Cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde, permeabilized with Triton X-100 and blocked with 1% BSA for 30 minutes at 37°C. Samples were incubated with primary antibody (1/200 in PBS + 1% BSA) for 1 hour at 37°C. An undiluted Alexa Fluor® 647-conjugated Goat anti-mouse IgG monoclonal was used as the secondary antibody.

    It is not known. From epitope mapping it has been shown to be directed against aa 21-40 of the HCV core region. I would suggest seeing how conserved this sequence is in 1a.
