Product Description

FGF-4 is a heparin-binding growth factor that is a member of the FGF family. Proteins of this family play a central role during prenatal development, postnatal growth and regeneration of a variety of tissues, by promoting cellular proliferation and differentiation. FGF-4 signals through FGFR 1c, 2c, 3c, and 4. Recombinant Human FGF-4 is a 19.7kD protein consisting of 182 amino acid residues. Recombinant corresponding to 182aa from human Fibroblast Growth Factor 4 expressed in E. coli Molecular Weight: ~19.7kD Biological Activity: Determined by a cell proliferation assay using Balb/c 3T3 cells. The expected ED50 is 10 ng/ml, corresponding to a specific activity of 1x10e5 units/mg.
