The surface antigen of Hepatitis B virus (HBV) is composed of Pre-S1, Pre-S2, and S domains. The longest surface antigen,
which has all the three domains, is called L protein, the middle sized antigen which has Pre-S2 and S domains,is called M protein,
and the smallest one conissted of S domain is called S protein. S protein is generally also called HBsAg. Pre-S1domian is known to
be the target molecule of HBV recptors expressed on human hepatic cell surface. On the otherhand, Pre-S2 domain is reportedly
related to HBV invasion into cells and carcinogenesis. Thus, Pre-S1 and Pre-S2 domains are becoming more and more important in
HBV research field.
The products are polyclonal antibodies raised in rabbits usingPre-S1 peptide. The antibody is good for western blot or ELISA.
