Hepatitis B virus (HBV) is a human pathogen, causing serious liver disease. The HBV surface protein antigens (HBsAg) are comprised of three carboxyl co terminal HBs proteins termed large (LHBs), middle (MHBs) and small (SHBs, also called major) protein. LHBs and MHBs also share the highly hydrophobic, repetitive, membrane spanning S domain. In addition, MHBs has a 55aa region called preS2.
Source:Recombinant protein corresponding to Hepatitis B Surface Antigen preS2, a single non-glycosylated polypeptide chain containing 55aa, expressed in E. coli.
