Cat#:  VAC-0306
Product Name:  Recombinant HBsAg preS1 Antigen
Description:  The E. coli derived Recombinant Hepatitis B Surface Antigen preS1 is a single non-glycosylated polypeptide chain containing 119 amino acids and having a molecular weight of 12.6 kDa.
Species:  HBV
Molecular Weight:  12.6 kDa
Source:  Escherichia Coli.
Introduction:  Hepatitis B virus (HBV) is a human pathogen, causing serious liver disease. The HBV surface protein antigens (HBsAg) are comprised of three carboxyl co terminal HBs proteins termed large (LHBs), middle (MHBs) and small (SHBs, also called major) protein. LHBs and MHBs also share the highly hydrophobic, repetitive, membrane spanning S domain. In addition, LHBs has a 119 amino acid region called preS1.
Purity:  Greater than 97.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
Formulation:  HBsAg protein was lyophilized from 0.2μm filtered (1mg/ml) solution in 20mM PB, pH 7.4, and 50mM NaCl.
Stability:  This lyophilized HBsAg preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C.Avoid repeated freeze/thaw cycles.
