  • RelevanceHepatitis B Virus (HBV) infection induces a disease state which manifests itself in a variety of ways, characterized by the extent of liver damage, inflammation and viral persistence. HBV infection is also associated with a 100 fold increased risk of hepatocellular carcinoma and currently infects over 250 million people worldwide. HBV has a partially double stranded 3.2 kilobase DNA genome which contains four open reading frames. One of these encodes a 154 amino acid protein called the HBx protein. HBx has been shown to be a transcriptional transactivator of both viral and cellular promoters. Lacking a DNA binding domain and nuclear localization signal, HBx is believed to exert transcriptional activity through protein protein interaction.

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...
