[Other]
Three types of hepatitis B virus surface antigen (HBsAg), L-, M-, and S-proteins are known. The L-protein is composed of S, Pre-S2, and Pre-S1 domains, and the M-protein iscomposed of S, Pre-S2 domains, and the S-protein S domain alone. L-protein plays an important role in HBV infection to human hepatic cells, where Pre-S1 region is the key for recognizing human hepatic cells. The "HBs Pre-S1 Quantitative Kit, high sensitivity" enables to explore the human hepatic cell recognizing activity of HBsAg and the HBV infectivity by determining Pre-S1 antigens.
The Pre-S1 region of surface antigen of HBV is known to play an important role in the recognition of human hepatocyte and resulting infection. We now commercialized a new kit that enables to quantitatively detect the Pre-S1 antigen with high sensitivity.
 Principle 
The key components of the kit are two anti-Pre-S1 mouse monoclonal antibodies and Pre-S1antigen. So-called sandwich system is employed, where antibody A captures the antigen on the microplate surface, and the captured antigen is detected by another antibody, antibody B which is labeled with HRP. Finally the amount of HRP attached was determined using chromatic substrate.
