Precipitation of chylomicrons and very low density lipoproteins from human serum with sodium lauryl sulfate

Abstract With appropriate concentration of sodium lauryl sulfate, VLDL from clear human sera and chylomicrons plus VLDL from lipemic sera are specifically precipitated at 35°C. The precipitated lipoproteins float on centrifugation and a clear subnatant is obtained. This precipitation requires the presence of a non-dialyzable thermolabile serum factor.
