Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against PBS, pH 7.4. Endotoxin Level <1 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Murine Interleukin-2 (rMuIL-2) to 0.1-1.0 mg/mL using sterile distilled water or aqueous buffer containing 0.1 % BSA. Storage & Stability Lyophilized recombinant Murine Interleukin-2 (rMuIL-2) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping Room temperature in continental US; may vary elsewhere. Background Interleukin-2 (IL-2) is a multi-faceted cytokine, known for promoting proliferation, survival, and cell death depending on the cell type and state. For example, IL-2 facilitates cell death only in activated T cells when antigen and IL-2 are abundant. The availability of IL-2 clearly impacts this process. IL-2 is retained in blood vessels by heparan sulfate, and that biologically active IL-2 is released from vessel tissue by heparanase. The morphologic changes and rapid cell death induced by dimeric IL-2 imply that cell death is mediated by disruption of membrane permeability and subsequent necrosis. IL-2 has a direct and unexpectedly broad influence on cellular homeostatic mechanisms in both immune and non-immune systems[1]. |
