Recombinant HBsAg, His-tagged

• Cat.No.: HBsAg-267H
• Product Overview: Recombinant HbsAg ayw full length is a 31kDa proteincloned from HBV 320 genome and fused to 6xHis Tag.

Specification

• Species: HBV
• Source: E.coli

• 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 clear solution. HBsAg ayw solution containing 7.5 mM phosphate buffer pH-7.2, 75 mM NaCl and 50% glycerol.
• Molecular Mass: 31kDa
• Purity: Greater than 90.0% as determined by SDS-PAGE.
• Stability: HBsAg Should be stored at 4°C between 3-4 weeks and for future use should be stored below -18°C.
• Full Length: Full L.

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.
