Description: Recombinant Mouse IL2 Protein is produced by E. coli expression system and the target gene encoding Ala21-Gln169 is expressed. Form: Lyophilized from a 0.2 μM filtered solution of 20mM Sodium Citrate, 5% Trehalose, pH 4.5. Gene Symbol: IL2 Alternative Names: Interleukin-2; IL-2; T-cell growth factor; TCGF; AldesleukinEntrez Gene (Mouse) : 16183SwissProt (Mouse) : P04351Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : MAPTSSSTSS STAEAQQQQQ QQQQQQQHLE QLLMDLQELL SRMENYRNLK LPRMLTFKFY LPKQATELKD LQCLEDELGP LRHVLDLTQS KSFQLEDAEN FISNIRVTVV KLKGSDNTFE CQFDDESATV VDFLRRWIAF CQSIISTSPQ Directions for Use : Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Quality Control : Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.Storage/Stability : Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months.
