Isolation of human serum HDL1 by zonal ultracentrifugation.

High density lipoprotein subfraction-1 (HDL(1)) is thought to interact with the high-affinity apoprotein B, E receptors of peripheral cells and may act as a modulator of LDL binding and uptake. In the present study the concentration and composition of HDL(1) in normal and hypercholesterolemic sera were studied using zonal ultracentrifugation. To permit… CONTINUE READING
