Abstract
THE synthesis of β-corticotropin has recently been reported by Schwyzer and Sieber1. This communication concerns the biological activity of this synthetic corticotropin in various experimental assay procedures. The synthetic corticotropin was compared with the Third International Standard2 and a commercial preparation of high purity (ACTH, Wilson Laboratories, Chicago, declared to have a potency of 95 I.U.).
