Hepatic synthesis of apo-B and apo-C and their binding to nascent very low density lipoproteins (VLDL) have been studied in fat-fed rats. Apolipoproteins were located in hepatocyte organelles by light and electron microscopy after immunoenzymatic staining using peroxidase-conjugated antibodies. Our results indicate that apo-B and apo-C are synthesized by membrane-bound ribosomes. Both apoproteins seem to be adsorbed simultaneously to the lipid core of VLDL in the lumen of the endoplasmic reticulum channels, at the junction zone between rough and smooth endoplasmic reticulum. Some additional protein presumably binds nascent VLDL in the Golgi apparatus as judged by the strong positive reaction of lipoprotein particles with peroxidase-labeled antibodies. Finally our data show that significant amounts of apo-B and apo-C are bound to the sinusoidal plasma membrane in fed rat livers which probably represent remnants of lipoprotein of intestinal origin since membrane-bound apolipoproteins virtually disappeared 24 h after lymphatic duct cannulation. It is suggested that nascent VLDL (apo-C poor) could be enriched in apo-C from lipoprotein remnants at the space of Disse.
