Description

Intended for preclinical researchers who may transition to GMP FGF basic/FGF2 for their clinical work

Measured in a cell proliferation assay using NR6R-3T3 mouse fibroblast cells. Raines, E.W. et al. (1985) Methods Enzymol. 109:749. The ED50 for this effect is 0.100-1.00 ng/mL.The specific activity of Recombinant Human FGF basic/FGF2 is >8.0 x 105 IU/mg, which is calibrated against the human FGF basic/FGF2 WHO International Standard (NIBSC code: 90/712).
