title: Epidermal growth factor: high and low molecular weight forms.
abstract: In crude homogenates of the submaxillary gland of the male mouse, epidermal growth factor (EGF) activity was found almost entirely in a high molecular weight complex (about 74,000 daltons). This high molecular weight form may be reversibly dissociated into EGF and an EGF-binding protein. EGF was found to have a molecular weight of approximately 6400. The EGF-binding protein has a molecular weight of 29,000, and shows arginyl-esterase activity.
