Cat#:RP-3976H;Product Name:Recombinant Human IFN a 2b Protein, HEK;Synonym:Interferon alpha 2b, IFNA, INFA2, MGC125764, MGC125765.;Description:IFN-a 2b Protein produced in HEK cells is a glycosylated monomer, having a total molecular weight of 16kDa. The IFN-a 2b is purified by proprietary chromatographic techniques.;Source:HEK.;Purity:Greater than 95% as obsereved by SDS-PAGE.;Bioactivity:The specific activity was determined by the dose-dependent cytotoxicity of the human TF-1 cell line (human erythroleukemic indicator cell line) and is typically 0.02-0.08ng/ml.;Formulation:The IFN-a 2b was lyophilized from 1mg/ml in 1xPBS.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized IFN-a 2b in sterile water not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized?IFN-a 2b although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IFN-a 2b 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.;
