Recombinant Hepatitis B virus HBsAg L-protein genotype C Protein

• Cat.No.: HBsAg L-14V
• Product Overview: Recombinant Hepatitis B virus HBsAg L-protein genotype C Protein was expressed in Saccharomyces cerevisiae. Particle (L-protein inserted in lipid bilayer) with mean particle size of about 70nm by dynamic light scattering method (about 20 nm by electronic microscope)

Specification

• Description: 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. Most of commercially available HBsAg is composed of either S-protein alone or a mixture of Sand M-proteins. The Pre-S1 region is known to be the hepatic cell recognition site and to be important in the HBV infection.
  The present product, HBsAg, L-protein (L antigen) is a particulate antigen composed of L protein, and can be used as a tool to investigate the mechanism of HBV infection, ELISA and others. Four major genotypes of products are available.
