Q&As

What size is the recombinant HBsAg? Is it the L, M or S version of the antigen?

The HBsAg proteins are generally provided in 100ug, 500ug, and 1mg packing sizes. We can also aliquot based on your specific requirements. Hepatitis B virus (HBV) expresses three types of surface antigens, i.e. S-, M-, and L-protein. L-protein is composed of S-, Pre-S2, and Pre-S1 region. The deletion of Pre-S1 region forms M-protein and further deletion of Pre-S2 region results in S-protein. As the sequence of the below antigens is confidential, we cannot tell that if they are L, M, or S versions.
