Effect of low density lipoprotein and high density lipoprotein on sodium dodecyl sulphate precipitation of very low density lipoprotein from human serum.

In the presence of low density lipoprotein, the sodium sodecyl sulphate(SDS)-very low density lipoprotein(VLDL) complex sedimented, while in the presence of high density lipoprotein the complex floated. This SDS-VLDL aggregate floats at serum triglyceride to cholesterol ratio of 0.7-0.9 and sediments at a ratio of 0.2-0.5.
