Recombinant human EGF is a bioactive growth factor protein intended for use in cell culture applications. Epidermal Growth Factor (EGF) plays an important role in the regulation of cell growth, proliferation, and differentiation of specific cells in vivo and serves as a potent mitogenic factor for a variety of culture cells of both ectodermal and mesodermal origin. The SBD recombinant human EGF is 6.2 kDa protein consisting of 54 amino acid residues.
