Recombinant human Fibroblast Growth Factor-1 is also known as acidic FGF (aFGF). FGF-1 is a bioactive protein intended for use in cell culture applications. It is involved in a number of biological processes including embryonic development, differentiation, survival, tissue repair and migration. FGF-1 is a heparin-binding member of the FGF superfamily of molecules. Its heparin-complex is an angiogenic agent in vivo and a potent mitogen for a variety of cell types in vitro. Recent study found that recombinant FGF1 (rFGF1) resulted in potent, insulin-dependent lowering of glucose levels in diabetic mice. Recombinant human FGF-acidic is a 15.8 kDa protein consisting of 140 amino acid residues.
