VLDL Lipoprotein particles have reduced cholesterol in EIIIA^–/–ApoE^–/– mice. (A) Plasma samples (n = 3-5) from ApoE^–/– and EIIIA^–/–ApoE^–/– mice were separated by FPLC. Fractions were assayed for cholesterol, and the mean of each fraction is presented. (B) Similar analysis of plasma from ApoE^+/+ mice. VLDL indicates very low density; LDL, low density, and HDL, high density lipoproteins, respectively. The x-axis shows milligrams per deciliter; y-axis, fraction number.
