ApoE and cholesterol levels in A34 and G37 mice. ApoE was assessed by western blotting and cholesterol levels were measured in plasma lipids of wild type, ΔTrsp, A34 and G37 mice. (A) Coomassie Blue staining of plasma proteins from wild type, ΔTrsp, A34 and G37 male mice (upper panel) and western blotting carried out using polyclonal anti-ApoE antibodies (lower panel). (B) Plasma cholesterol levels. Values represent means ± SE, n = 5 mice/genotype for wild type and ΔTrsp mice and n = 4 mice/genotype for A34 and G37 mice (*, p < 0.01).
