Cat#:RP-2160H;Product Name:Recombinant Human B2M Protein Recombinant;Synonym:Beta-2-microglobulin, B2M.;Description:B2 Microglobulin Protein produced in E.coli is a non-glycosylated polypeptide chain having a molecular mass of 11.76 kDa. The B2M is purified by proprietary chromatographic techniques.;Source:E.coli;Purity:Greater than 95.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.;Bioactivity:Please contact us for detailed information;Formulation:The protein was lyophilized from a concentrated solution (1mg/ml) containing PBS (pH 7.4) and 0.05% NaN3.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized B2M in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized B2M although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution B2M should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.;
