Description

Measured in a cell proliferation assay using MC/9-2 mouse mast cells. Thompson-Snipes, L. et al. (1991) J. Exp. Med. 173:507. The ED50 for this effect is 0.0750-0.750 ng/mL.

The specific activity of recombinant human IL-10 is >2.50 x 106 units/mg, which is calibrated against the human IL-10 WHO Reference Reagent (NIBSC code: 93/722).
