Cat#:RP-3614H;Product Name:Recombinant Human HBcAg 1-149 a.a.;Synonym:HBcAg ;Description:HBcAg subtype adw2 produced in E.coli, is a single, non-glycosylated, polypeptide chain containing 1-149 amino acids and having a molecular weight of approximately 20kDa. HBcAg adw2 1-149 protamine-like domain was truncated in order to enhance the differentiation of anti-HBe in ELISA test. HBcAg was purified by proprietary chromatographic techniques.;Source:E.coli;Purity:Greater than 95.0% as determined by SDS-PAGE.;Formulation:Phosphate buffered saline, pH 7.4.;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.;
