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 consisted of S domain is called S protein. S protein is generally also called HBsAg. Pre-S1 domian 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 recombinant peptides having Pre-S1 domian. Two types of peptides are available; one has no tag peptide, and the other is fusion peptide with a tag-peptide. Chose either one suitable for your research purpose.
