Fully biologically active when compared to standard. The ED50 as determined by inhibiting IL-1α- dependent proliferation of murine D10S cells is less than 40 ng/ml, corresponding to a specific activity of > 2.5 x 10 ^ 4 IU/mg in the presence of 50 pg/ml rHuIL-1α.

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
