Abstract
Three immunochemically and electrophoretically distinct lipoproteins, LP-A, LP-B, and LP-X,1 were isolated from the low density lipoprotein fraction (1.006-1.063 g/ml) in plasma from patients with biliary obstruction by a separation procedure which combines ultracentrifugation, heparin precipitation, and ethanol fractionation. This method, here described, permits the quantitative determination of individual plasma lipoprotein families on the basis of their protein moieties, rather than on the basis of their lipid moieties or density.
