αs0-Casein: its preparation and characterization

Abstract

It has been reported previously (Annan & Manson, 1969) that chromatography of the αs-casein complex of bovine milk on columns of sulphoethyl Sephadex C-50 resulted in fractionation of the complex into a main component, αs1-casein and a number of minor components one of which was designated αs0-casein. The present communication describes the preparation of αs0-casein from unfractionated casein in an amount and state of purity which render possible its further characterization.
