Description

Carrier Free Recombinant Protein

Measured by its ability to inhibit LIF-dependent proliferation of TF-1 human erythroleukemic cells. Kitamura, T. et al. (1989) J. Cell Physiol. 140:323. The ED50 for this effect is typically 0.7-7 μg/mL in the presence of 0.3 ng/mL of recombinant human LIF.
