Description

Animal-Free.

Measured in a cell proliferation assay using PHA-activated human peripheral blood lymphocytes (PBL). Yokota, T. et al. (1986) Proc. Natl. Acad. Sci. USA 83:5894. The ED50 for this effect is 0.100-0.500 ng/mL.The specific activity of Recombinant Human IL-7 is >1.00 x 108 units/mg, which is calibrated against the human IL-7 reference standard (NIBSC code: 90/530).
