THE STIMULATION OF LEUCINE-2-C14INCORPORATION INTO THE PROTEIN OF ISOLATED RAT DIAPHRAGM BY SIMIAN GROWTH HORMONE ADDEDIN VITRO1

Abstract

Simian growth hormone, when added in vitro in low concentrations, consistently and significantly stimulated the incorporation of leucine-2-C¹⁴ into the protein of isolated diaphragms of hypophysectomized rats. In contrast, equivalent concentrations of bovine and porcine growth hormone preparations only occasionally produced a similar response.
