EGF (R709) polyclonal antibody

Epidermal growth factor (EGF) is an acid- and heat-stable 53 amino acid protein of 6 kDa originally found in rodents and humans. EGF has been shown to be a potent mitogen for a variety of cell types both in vivo and in vitro. It binds to the 170 kDa EGF receptor on the surface of cells and mediates intrinsic phos phoryl ation of the receptor on tyrosine residues. EGF has been detected in nearly all body fluids such as urine (urogastrone), saliva, milk and platelet-rich plasma.
