Abstract

Abstract Three different isocratic systems for the separation by reversed-phase high-performance liquid chromatography (HPLC) of different species of insulin have been investigated. The effect of different solvent compositions and temperatures on elution time and resolution have been studied. These studies have been used to devise a method for reversed-phase liquid chromatographic separation of bovine, porcine, and human insulin, as well as the A and B chains of bovine insulin. The method can also be used for the separation of the various products of the iodination of porcine insulin. 125I-A14 tyrosine-labeled porcine insulin can be readily separated from nonlabeled porcine insulin and from other idoinated constitutents of the mixture. A flow-though gamma-counting system that was designed for this work is described.
