Hepatitis B Surface Antigen ayw subType, SaccharoMyces (Recombinant)

Recombinant Hepatitis B Surface Antigen, ayw subtype (HBsAg-ayw)

HBsAg is the surface antigen of the Hepatitis-B-Virus (HBV). The capsid of 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.

Recombinant HbsAg ayw full length is a 24kDa protein cloned from HBV 320 genome. The Saccharomyces cerevisae derived recombinant full length protein contains the HBV surface antigen, having an Mw of 18kDa (ayw) and is fused to 6 His Tag at C-terminus. HBsAg runs as a multimer on SDS-PAGE.
