Measured in a cell proliferation assay using CTLL-2 mouse cytotoxic T cells. Gearing, A.J.H. and C.B. Bird (1987) in Lymphokines and Interferons, A Practical Approach. Clemens, M.J. et al . (eds): IRL Press. 295. The ED50 for this effect is 0.0300-0.250 ng/mL. The specific activity of recombinant human IL-2 is 5.00 x 106 IU/mg, which is calibrated against an internal reference standard value assigned against the human IL-2 WHO International Standard (NIBSC code: 86/500).
