Physical Appearance and Stability Lyophilized Interleukin-2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL2 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 prevent freeze-thaw cycles.
Formulation and Purity The protein (1mg/ml) was lyophilized after extensive dialysis against 20mM PBS pH=7.4. Greater than 97.0% as determined by
Application
Solubility It is recommended to reconstitute the lyophilized Interleukin 2 in 20mM AcOH not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Biological Activity The ED50 as determined by the dose-dependant stimulation of murine CTLL-2 cells is < 0.1 ng/ml, corresponding to a Specific Activity of 10,000,000 IU/mg.
Shipping Format and Condition Lyophilized powder at room temperature.
