Description
Product outline
Owing to deep research experience in HBV envelop, Beacle launches quantitative ELISA kits targeted to varous HBsAg domains. Three types of HBsAg is known; named S-, M- and L-antigen. L-antigen is consisted of S, Pre-S2 and Pre-S1 domains, M-antigen of S and Pre-S2 domains, and S-antigen of S domain alone. These domains play important role in HBV infection. Pre-S1 domain is known to be the key element in recognizing hepatic cells, Pre-S2 and S is important in cellular invasion fo HBV. The serum level of S-antigen (or S-domain) is well studies as a tool to daignose the HBV infection, but almost no study was conducted to examine the serum level of Pre-S1 and Pre-S2. Beacle, by marketing ELISA kit to detect these domains, wishes to contribute studies of HBV infection.
Products listed in this page can be ordered directly to us through oder form, or can be odered through our distributors B-Bridge International (USA, Europe), Takara-Bio, Cosmobio, or Funakoshi.
