Cat#:RP-1819M;Product Name:Recombinant Mouse IL2 Protein;Synonym:Interleukin-2, T-cell growth factor (TCGF), Aldesleukin, Lymphokine, IL-2.;Description:Recombinant mouse Interleukin-2 / IL2 protein produced in E.coli is a single, non-glycosylated polypeptide chain containing 148 amino acids and having a molecular mass of 17.2kDa. The recombinant mouse IL2 protein is purified by oour proprietary chromatographic techniques.;Source:E.coli;AA Sequence:PTSSSTSSST AEAQQQQQQQ QQQQQHLEQL LMDLQELLSR MENYRNLKLP RMLTFKFYLP KQATELKDLQ CLEDELGPLR HVLDLTQSKS FQLEDAENFI SNIRVTVVKL KGSDNTFECQ FDDESATVVD FLRRWIAFCQ SIISTSPQ.;Purity:Greater than 97.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.;Bioactivity:The ED50 of mouse IL2 protein as determined by the dose-dependant stimulation of murine CTLL-2 cells is less than 0.2ng/ml corresponding to a Specific Activity of 5x106IU/mg.;Formulation:Recombinant mouse IL2 protein was lyophilized from a 0.2µm filtered concentrated solution (1mg/ml) in 20mM PBS, pH 7.4.;Stability:Recombinant mouse IL2 Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized Mouse IL-2 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized recombinant mouse Interleukin-2 / IL2 protein although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution recombinant mouse IL2 protein 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 avoid freeze-thaw cycles.;
