FGF-basic is one of 23 known members of the FGF family. Proteins of this family play a central role during prenatal development and postnatal growth and regeneration of a variety of tissues, by promoting cellular proliferation and differentiation. FGF-basic is a non-glycosylated heparin binding growth factor that is expressed in the brain, pituitary, kidney, retina, bone, testis, adrenal gland liver, monocytes, epithelial cells and endothelial cells. FGF-basic signals through FGFR 1b, 1c, 2c, 3c and 4. Recombinant rat FGF-basic is a 16.3kD protein consisting of 145aa.

Recombinant protein corresponding to rat FGF-basic, expressed in E.coli.
Biological Activity
Determined by a cell proliferation assay using Balb/c 3T3 cells. The expected ED50 is ≤ 0.2 ng/ml, corresponding to a specific activity of ≥5x10e6 units/mg.
