HBsAg, Pre-S2 peptide Thioredoxin-His Tag

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 recombinant peptides having Pre-S2 domian. Twotypes of peptides are available; one has no tag peptide, and

the other is fusion peptide with a tag-peptide. Chose eihter one suitable for your research purpose.
