DESCRIPTION

HbsAg subtype adw2 produced in E.Coli, is a single, non-glycosylated, polypeptide chain containing 226 amino acids and having a molecular weight of approximately 23.0kDa. HBsAg adw2 migrates on SDS-PAGE as a 23kDa monomer band with minor amounts of dimer (46kDa) and trimer (69kDa) forms.
The HBsAg is fused to a 6 His tag on C-terminus and purified by proprietary chromatographic techniques.

SOURCE
