Physical Appearance and Stability: Lyophilized IFNW1 although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution IFNW1 should be stored at 4C between 2-7 days and for future use below -18C.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: Lyophilized from a 0.2um filtered concentrated solution in PBS, pH 7.4. Greater than 95.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
Solubility: It is recommended to reconstitute the lyophilized IFNW1 in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Biological Activity: The ED50 was determined by a cytotoxicity assay using Human TF-1 cells is < 0.01 ng/ml, corresponding to a specific activity of > 100, 000, 000 units/mg.
