|Product Overview:||Recombinant Human CSF1, Glu33-Ser190, was produced in E. coli using non-animal reagents in an animal-free facility under cGMP guidelines.|
|Form:||Lyophilized from a 0.2 μm filtered solution in PBS.|
|Bio-activity:||Measured in a cell proliferation assay using M‑NFS‑60 mouse myelogenous leukemia lymphoblast cells. Nakoinz, I. et al. (1990) J. Immunol. 145:860. The ED50 for this effect is typically 0.5-1.5 ng/mL.
The specific activity of Recombinant Human M-CSF is approximately 1.68 x 10^5 IU/μg, which is calibrated against recombinant human
M-CSF WHO International Standard (NIBSC code: 89/512).
