title: Evidence for the presence of the pituitary insulin secretagogue beta-cell trophin in human plasma.
abstract: It has been demonstrated that the insulin secretagogue beta-cell-trophin, ACTH(22-39), is present in human plasma. The hormone, separated from plasma by affinity chromatography on a corticotrophin-like intermediate-lobe peptide antibody column, behaves similarly to synthetic beta-cell-trophin on a gel filtration column and on reverse-phase high-performance liquid chromatography. Sufficient amounts of the hormone were isolated from the plasma of two patients with Nelson's syndrome to demonstrate its biological activity on the perfused rat pancreas.
