General Info

    • HBsAg
  • RelevanceHepatitis 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.

Product Wall

Per the lab, this product is an aggregated protein that without heating would run as monomers, dimers and multimers on Western Blots and in SDS-PAGE.

Per the lab, the antigen assembles into particles and they recommend sonication, but please be advised, they have not performed this.

Here are a few specific sELISA protocol details I was able to find:

ab2039, the capture antibody, was coated on the plate at 5 μg/ml in 0.1 M carbonate buffer, and the HRP-conjugated detection antibody, ab2042, was used at 0.5-5 ug/mL. Read More

If you don't mind providing a more complete protocol for the ELISA assay you ran, I can help you to troubleshoot further.

We have already tested ab2039 to work successfully with ab2042 in sandwich ELISA.

We have not yet de...
