Hepatitis B Virus Surface Antigen (HBsAg) L-protein ST type (Recombinant)

Beacle has been a leader in devloping original hepatitis B virus-related products for over 10 years.All HBsAgs are made from recombinant yeast. These products are non-infective, and can be used safely as antigens or HBV mimetic for research and diangostic purposes.HBsAg L-protein (Cat # BCL-AG-01) contains all Pre-S1, Pre-S2 and S regions.ST-type L-protein (Cat # BCL-AGS-01, BCL-AGS-02) also contains all Pre-S1, Pre-S2 and S regions, but the antigenecity of S region is reduced by exhcnaging some amino acid in this region.HBsAg-XT (Cat # BCL-AGX-01, BCL-AGX-02) is composed of full S region and a part of Pre-S2 region. This antigen shown highly strong S-antigen activity by ELISA assay and ideal as standard antigen.
