ApoE levels in 85-day-old apoEm/4 and APPPS1-21/apoEm/4 brains. The cortices were homogenized in PBS, followed by 1 % Triton X-100 and 5 M guanidine and apoE levels were measured by ELISA. a-b Absolute concentrations and fractional distribution of mouse apoE and apoE4 in apoEm/4 mice (n = 10). c-d Absolute concentrations and fractional distribution of mouse apoE and apoE4 in APPPS1-21/apoEm/4 mice (n = 10; *p < 0.05; **p < 0.01; ***p < 0.001, Two-way ANOVA for repeated measures followed by Bonferroni post-test). e-g Correlations of Aβ42 with mouse apoE, apoE4 and Aβ40 in the insoluble fraction of APPPS1-21/apoEm/4 cortices (n = 10)
