Purity ~95% (SDS-PAGE gel, HPLC). KGF/FGF-7 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. KGF/FGF-7 is a mitogen factor specific for epithelial cells and keratinocytes. KGF/FGF-7 signals through FGFR 2b. KGF/FGF-7 plays a role in kidney and lung development, angiogenesis, and wound healing. Recombinant human KGF/FGF-7 is a 18.9kD protein consisting of 163 amino acid residues. Source: Recombinant protein corresponding to human KGF expressed in E. coli. Biological Activity: Determined by the dose-dependent stimulation of thymidine uptake by KGF-responsive BaF3 cells.
