Alias	protein/Z02815-Hepatitis_B_Surface_Antigen_preS1_HBsAg-preS1, 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.</td></tr><tr><th>M.W.</th><td colspan="7"> Approximately 12.6 kDa, a single non-glycosylated polypeptide chain containing 119 amino acids.</td></tr><tr><th>Purity</th><td colspan="7"> >95% by SDS-PAGE and HPLC analyses.</td></tr><tr><th>Endotoxin Level</th><td colspan="7"> Less than 0.2EU/ug of rHBsAg-preS1 as determined by LAL method.</td></tr><tr><th>Storage</th><td colspan="7"> T This lyophilized preparation is stable at 2-8 C, but should be kept at -20 C for long term storage, preferably desiccated.
