| Description | Interleukin-2 Mouse Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 170 amino acids (21-169 a.a) and having a molecular mass of 19.5kDa. The mouse IL-2 is fused to a 20 amino acid His tag at N-Terminus and purified by proprietary chromatographic techniques. |
| Expression host | Escherichia Coli. |
| Formulation | The Mouse IL2 protein (0.5mg/ml) is supplied in Phosphate Buffered Saline (pH7.4) 0.1M NaCl, and 20% glycerol. |
| Protein Background | IL2 is a secreted cytokine that is important for the proliferation of T and B lymphocytes. The receptor of this cytokine is a heterotrimeric protein complex whose gamma chain is also shared by interleukin 4 (IL4) and interleukin 7 (IL7). The expression of this gene in mature thymocytes is monoallelic, which represents an unusual regulatory mode for controlling the precise expression of a single gene. The targeted disruption of a similar gene in mice leads to ulcerative colitis-like disease, which suggests an essential role of this gene in the immune response to antigenic stimuli. |
| Purity | Greater than 90.0% as determined by SDS-PAGE. |
| Reagent Appearance | Sterile Filtered colorless clear solution. |
| Stability | Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. Please avoid freeze thaw cycles. |
| Synonyms | Interleukin-2, T-cell growth factor (TCGF), Aldesleukin, Lymphokine, IL-2, Il2. |
