Abstract
The main apolipoproteins of plasma high-density lipoproteins (HDL) and low-density lipoproteins (LDL) were analyzed by capillary electrophoresis. Where possible the results were compared with slab sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis. Addition of the detergent SDS to the running buffer was essential for separation. Separations were carried out in bare silica and polyacrylamide-coated capillaries. The main apolipoproteins of HDL could be separated in an uncoated capillary filled with borax buffer containing 0.1% SDS. Using the coated capillary, a mixture of HDL and LDL apolipoproteins was resolved in less than 12 min. These preliminary studies indicate that capillary electrophoresis is a promising technique for screening plasma apolipoproteins.
