Target

  • Relevance

    Hepatitis B Virus (HBV) infection induces a disease state characterised by liver damage, inflammation and viral persistence. Infection also increases the risk of hepatocellular carcinoma. HBV belongs to the Hepadnaviridae family of viruses. Its genome consists of partially double stranded circular DNA. The DNA is enclosed in a nucleocapsid, or core antigen (HBcAg), which is surrounded by a spherical envelope (surface antigen or HBsAg). The core antigen shares its sequences with the e antigen (HBeAg) but no cross reactivity between the two proteins has been observed. The HBV genome also encodes a DNA polymerase that also acts as a reverse transcriptase. Hepatitis B infection is normally diagnosed from serological tests that detect HBsAg but as the disease progresses this antigen may no longer be present in the blood and tests for HBcAg are used. If HBsAg can be detected in the blood for longer than six months, chronic hepatitis B is diagnosed. The antigenic determinant of the protein moiety of the HBsAg determines specific characteristics of different serotypes and provides the basis of immunodetection. HBsAg has antigenic heterogeneity, specifically, two pairs of sub specific determinants, d/y and w/r allow the following combinations: adw, ayw, adr, ayr.

    Question

    I have been using this antibody in Flow Cytometry. I have sucessfully stained infected cells, however I am detecting positive signal in healthy control cells as well. I have tested multiple fixation methods as well as antibody dilutions of 1:10 - 1:100. I would like to try another lot of antibody.

    Asked on Sep 02 2011

    Answer

    Thank you for your enquiry. I can confirm that ab20930 Anti-Hepatitis B Virus Surface Antigen (Ad/Ay) antibody is a goat polyclonal antibody. Is is very unusual to have isotype controls for polyclonal antibodies, becuase they contain a mixture of isotypes. Therefore, regrettably we do not have a goat polyclonal isotype control available in the catalogue. I am sorry there are no suitable isotype controls to meet your requirements on this occasion. Should you have any further questions, please do not hesitate to contact us.
