title: Cholesterol in high-density lipoproteins: a comparison between dextran sulfate-magnesium chloride precipitation and preparative ultracentrifugation.
abstract: The cholesterol in high density lipoproteins (HDL) has been determined in 140 serum samples after dextran sulfate-magnesium chloride precipitation of the apolipoprotein B-containing lipoproteins. The values correlated well with simultaneously measured values from preparative ultracentrifugation (slope 0.98, r = 0.93). Furthermore, there was a significant correlation in 60 specimen between the dextran sulfate-MgCl2 and heparin-MnCl2-precipitation method.
