Purification and characterization of bovine lipoproteins: resolution of high density and low density lipoproteins using heparin-Sepharose chromatography
SR Cordle, RA Clegg and SJ Yeaman
The selective and reversible adsorption of bovine low density lipoproteins
(LDL) by heparin-Sepharose has been exploited as the critical step in a
procedure for the preparative isolation of very low density lipoproteins
(VLDL)/chylomicrons, LDL, and high density lipoproteins (HDL) from bovine
plasma. Molecular size exclusion chromatography and isopycnic density
gradient separation steps are also involved in the method described. The
resulting HDL and LDL fractions are free from contamination by one another
as judged by electrophoretic mobility in agarose gels. The major lipid and
apolipoprotein compositions of the three resolved lipoprotein classes have
been determined.
