Evaluation of a simple protein free medium that supports high levels of monoclonal antibody production.

abstract：:Previously, it has been shown that the binding of epidermal growth factor (EGF) by a wide range of cells decreases as cell density increases. In this report, we demonstrate that KB cells treated chronically with phorbol esters continue to exhibit decreases in EGF receptor binding as cell density increases. This findin...
