Starch gel electrophoresis at alkaline pH of bovine growth hormone preparations from a number of sources has revealed a common pattern characterized by a major anionic component and two minor faster moving components. Gel filtration studies of the hormone indicate that all three components are of similar molecular weight. A method has been developed for separation of the components by chromatography on diethylaminoethyl Sephadex. All three components were biologically active and displayed similar amino acid compositions.
