Four mouse monoclonal antibodies specific for human epidermal growth factor (EGF) receptors have been prepared using EGF receptor protein from human A431 epidermoid carcinoma cells as immunogen. We(More)
Epidermal growth factor (EGF) at 3 nM maximally inhibits the proliferation of A431 epidermoid carcinoma cells. We show that at lower concentrations, in the range of 3-100 pM, EGF has a mitogenic(More)
