Recombinant Hepatitis B virus HBsAg S adr Protein

• Cat.No.: HBsAg S adr-16V
• Product Overview: Recombinant Hepatitis B virus HBsAg S adr Protein was expressed in Saccharomyces cerevisiae. Particle (S-protein inserted in lipid bilayer) with mean particle size of about 45nm by dynamic light scattering method.

Specification

• Species: Hepatitis B virus
• Source: S.Cerevisiae
• 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. HBsAg S-protein is a particulate antigen composed of S-protein, and widely used as active substance of HBV vaccine, and as a important diagnostic marker of HBV infection.
  The present products, HBsAg S-protein can be used as a tool to investigate the mechanism of HBV infection, immunoassays and others. Two subtypes, adr and adw are available.
• Form: liquid form (10mM sodium phosphate, 140mM NaCl, pH6.4, 0.1% sodium azide).
• Purity: over 95%
• Usage: Standard antigen for ELISA, western, and others
• Storage: 4 centigrade
• Warning: The antigen may be adsorbed on plastic tubes especially low concentration (below 100ng/mL). Please use protein low bind tubes at lower concentration.

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.
