| Solubility | It is recommended to reconstitute the lyophilized IL-2 in Sterile 10 mM sodium bicarbonate, pH 8.5 at 0.1 mg/mL, which can then be further diluted to other aqueous solutions. | ||
| Stability | Lyophilized IL-2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C . Upon reconstitution IL-2 should be stored at 4°C between 2-7 days and for future use below -18°C .Please prevent freeze-thaw cycles. | ||
| Biological Activity | The ED50, as determined by CTLL-2 cell proliferation is <5ng/ml corresponding to a specific activity which is ≥ 2.0 x 10^5 units/mg. | ||
| Formulation | The protein was lyophilized from a sterile (0.2µm) filtered solution containing 20 mM sodium bicarbonate, pH 8.5. | ||
IL2 is a secreted cytokine that is essential 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 and interleukin 7. The expression of IL2in mature thymocytes is monoallelic, which represents an unusual regulatory mode for controlling the exact expression of a single gene.
The ED50, as determined by CTLL-2 cell proliferation is <5ng/ml corresponding to a specific activity which is ≥ 2.0 x 10^5 units/mg.
Lyophilized IL-2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C . Upon reconstitution IL-2 should be stored at 4°C between 2-7 days and for future use below -18°C .Please prevent freeze-thaw cycles.
