Comparative Investigations of Different Human Growth Hormone Preparations

Abstract

Human growth hormone preparations used for treatment of pituitary dwarfism have been isolated in several laboratories using different methods. In this report the gelchromatographic purity of four such growth hormone preparations will be described. In addition the radioimmunoassayable growth hormone content of the different preparations and their lipolytical activity in vitro have been measured. Noteworthy differences among the growth hormone preparations used for therapy were found.
