|HB Pre-S1 Antigen Quantitative ELISA Kit High Sensitivity (2x96well)
||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.
