Aβ ELISA assay of whole brain homogenates show no differences in Aβ levels by genotype. Aβ levels in 8-, 9-, 15- and 16 to 18-month-old with normal LRP1 levels (APPswe/PS1dE9(+)/LRP1lox/lox) were compared to those with lower LRP1 levels (GFAP-Cre +). There was no difference in Aβ levels by genotype by age (p values range 0.40 to 0.90 based on Student's t-test). ELISA data used to generate the graph are shown in Table 1, which includes information on the number of animals used at each age.
