The ED50 as determined by the dose-dependant stimulation of D10.G4.1 mouse helper T cells is typically 3-10pg/mL.
The protein was lyophilized with 1x PBS pH-7.4
Sterile Filtered White lyophilized (freeze-dried) powder.
Greater than 98.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
It is recommended to reconstitute the lyophilized IL1B in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Lyophilized IL1B although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution IL1B should be stored at 4oC between 2-7 days and for future use below -18oC. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please avoid multiple freeze-thaw cycles.
