HBsAg is the surface antigenof the Hepatitis-B-Virus (HBV). The capsidof a virus has different surface proteins from the rest of the virus. The antigen is a protein that binds specifically on one of these surface proteins. It is commonly referred to as the Australian Antigen.
HBsAg is a serological marker produced on the surface of the hepatitis B virus and is one of the first disease state markers to be detected in the serum of patients infected with the hepatitis B virus. Recombinant Anti HbsAg produced in E.Coli is a non-glycosylated, polypeptide chain containing?an amino-terminal hexahistidine tag and a carboxyterminal kappa constant region tag and having a molecular weight of 43 kDa.
HBsAg is purified by proprietary chromatographic techniques.
