Recombinant HBV HBsAg protein, His-tagged

• Cat.No.: HBsAg-233H
• Product Overview: Recombinant HBsAg subtype adw2 protein, fused to His-tag at C-terminus, was expressed in E.coli and purified by proprietary chromatographic techniques.

Specification

• Species: HBV
• Source: E.coli
• Tag: His
• Protein Length: 226
• Description: HBsAg is the surface antigen of the Hepatitis-B-Virus (HBV). The capsid of a virus has different surface proteins from the rest of the virus. The antigen is a protein that binds specifically on one of these surface proteins. It is commonly referred to as the Australian Antigen.
• Form: Sterile filtered solution containing 50mM arginine and 1M urea.
• Molecular Mass: 23.0kDa
• Purity: Greater than 90.0% as determined by SDS-PAGE.
• Storage: Store at 4 centigrade if entire vial will be used within 2-4 weeks. Store, frozen at -20 centigrade for longer periods of time.
  For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
  Avoid multiple freeze-thaw cycles.

Gene Information

• UniProt ID: Q17UT6

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.
