Apolipoprotein B variant derived from rat intestine.

Abstract
A variant of apolipoprotein B was observed in the lymph lipoproteins [chylomicrons, very low density lipoproteins (VLDL) and low density lipoproteins (LDL)] of rats, in the plasma VLDL of fed rats and in the plasma VLDL and LDL of rats fed a high-fat, high-cholesterol diet. It is the sole apolipoprotein B in the chylomicrons and VLDL of lymph. It differs from the apolipoprotein B of normal plasma LDL in its immunological properties and in its apparent MW from electrophoresis on 3.5% NaDodSO4/polyacrylamide gel.
