Stimulates the growth of NRK-1 cells in soft agar at concentrations ranging from 0.1 to 5 ng/ml corresponding to a specific activity of 200,000-10,000,000 IU/mg. Effective concentration ranges must be experimentally determined. Purified EGF and/or TGF- must be present for observation of The Biological activity.
