Cat#:RP-3627H;Product Name:Recombinant Human HBsAg adw2;Synonym:HBsAg;Description:HbsAg subtype adw2 produced in E.coli, is a single, non-glycosylated, polypeptide chain containing 226 amino acids and having a molecular weight of approximately 23.0kDa. HBsAg adw2 migrates on SDS-PAGE as a 23kDa monomer band with minor amounts of dimer (46kDa) and trimer (69kDa) forms. The HBsAg is fused to a 6 His tag on C-terminus and purified by proprietary chromatographic techniques.;Source:E.coli;Purity:Greater than 90.0% as determined by SDS-PAGE.;Formulation:Sterile filtered solution containing 50mM arginine and 1M urea.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Storage:Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.;
