Recombinant HBsAg adr, AF488 labeled

• Cat.No.: HBSAg-253HAF488
• Product Overview: Recombinant HBsAg adr produced in CHO cells. The protein was labeled with AF488 in vitro.

Specification

• Species: HBV
• Source: CHO
• Description: A protein on the surface of hepatitis B virus that can be detected in high levels in serum during acute or chronic hepatitis B virus infection. The presence of HBsAg indicates that the person is infectious, except when it might be transiently positive within 30 days after a dose of hepatitis B vaccine (HepB). The body normally produces antibodies to HBsAg as part of the normal immune response to infection. HBsAg is the antigen used to make HepB vaccine.
• Conjugation/Label: AF488
• Molecular Mass: The molecular weight is approximately 23-27 kDa
• Purity: > 95% by SDS-PAGE
• Storage: HBsAg Should be stored at 4 centigrade, DO NOT FREEZE.
• Concentration: 1.0 mg/mL
• Storage Buffer: PBS buffer

Gene Information

• Official Symbol: HBSAg
• Synonyms: Hepatitis B surface antigen; HBSAg

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.
