Supplier:  R&D Systems™ 255SC050

Catalog No. 255SC050

Description

Measured in a cell proliferation assay using TF-1 human erythroleukemic cells. Kitamura, T. et al. (1989) J. Cell Physiol. 140:323. The ED50 for this effect is 1-5 ng/mL. The specific activity of Recombinant Human SCF is approximately 1.3 x 106 IU/mg, which is calibrated against recombinant human SCF WHO International Standard (NIBSC code: 91/682). Specific activity is for reference purposes only and is not routinely tested.
