Analyses of the plasma lipoproteins in hABCA1-Tg × apoE-KO and
apoE-KO mice maintained on a regular chow diet. (A) The
distribution of cholesterol in different FPLC elution fractions was
analyzed after separation of the plasma lipoproteins present in pooled
plasma from female apoE-KO (■; n = 5)
and hABCA1-Tg × apoE-KO (○; n = 5)
mice by FPLC. ApoA-I, apoA-II, and apoB present in FPLC fractions
corresponding to VLDL (lanes 1 and 2), IDL/LDL (lanes 3), and HDL
(lanes 4) elution volumes (16, 17, 22.5, and 31 ml, respectively) were
determined by immunoblot analysis (Inset).
(B) Two microliters of plasma from C57BL/6 (C),
apoE-KO (E-KO), and hABCA1-Tg × apoE-KO (E-KO × hABCA1-Tg)
mice were analyzed by native agarose gel electrophoresis followed by
staining with fat red B. (C) Detection of apoA-I by
immunoblotting after two-dimensional gel electrophoresis of plasma from
apoE-KO and hABCA1-Tg × apoE-KO mice.
