Isolation and analysis of lipoproteins secreted by rat liver hepatocytes.

A procedure has been developed for the small-scale isolation and characterization of lipoproteins secreted by cultured rat liver hepatocytes. The lipoproteins in the culture medium were separated into VLDL, LDL, HDL and a fraction with d greater than 1.21 on single-spin density-gradients. The lipoproteins were removed from the gradients by adsorption onto… (More)
