Cat#:RP-4025H;Product Name:Recombinant Human IL15 Protein;Synonym:IL-15, MGC9721.;Description:Interleukin-15 Protein produced in E.coli is a single, non-glycosylated polypeptide chain containing 114 amino acids (and an N-terminal Methionine) and having a molecular mass of 12.8kDa. The IL-15 is purified by proprietary chromatographic techniques.;Source:E.coli;AA Sequence:MNWVNVISDL KKIEDLIQSM HIDATLYTES DVHPSCKVTA MKCFLLELQV ISLESGDASI HDTVENLIIL ANNSLSSNGN VTESGCKECE ELEEKNIKEF LQSFVHIVQM FINTS.;Purity:Greater than 97.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis SDS-PAGE.;Bioactivity:The ED50 as determined by the dose-dependant stimulation of the proliferation of mouse CTLL-2 was found to be < 0.5 ng/ml, corresponding to a Specific Activity of 2 x 106 IU/mg.;Formulation:The protein was lyophilized from PBS pH 7.4.;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.;
