Abstract

A process of isolating beta-lipoproteins from blood serum in about 99% purity comprising precipitating beta-lipoproteins from blood serum substantially free of chylomicrons with polyanethole sulfonate and a divalent cation, forming a solution of the beta-lipoproteins and reprecipitating them with the divalent cation, again forming a solution of said beta-lipoproteins and passing them through a DEAE cellulose column. The beta-lipoproteins purified by the method are particularly suited as a calibration standard for use in assays of the beta-lipoprotein content of blood serum.
