Cat#:RP-1809M;Product Name:Recombinant Mouse IL15 Protein;Synonym:IL-15, MGC9721.;Description:Interleukin-15 Mouse Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 115 amino acids and having a molecular mass of 13321 Dalton. The IL-15 is purified by proprietary chromatographic techniques.;Source:E.coli;AA Sequence:The sequence of the first five N-terminal amino acids was determined and was found to be Met-Asn-Trp-Ile-Asp.;Purity:Greater than 95.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.;Bioactivity:The ED50 as determined by the dose-dependant stimulation of the proliferation of mouse CTLL-2 was found to be 15 ng/ml, corresponding to a Specific Activity of 2 x 105 IU/mg.;Formulation:The protein was lyophilized from a concentrated (1mg/ml) solution with 10mM NaP pH 8.0.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized Interleukin-15 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized Interleukin-15 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL15 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.;
