(A–E) Aβ1–40 and Aβ1–42 levels were measured in Young (A–C) or Old (D–F) Mock-, SDPM1-, and SDPM2-immunized mice (with adjuvant) in cortex (A, D), hippocampus (B, E), or cerebellum (C, F). (G) Immunoblot with an Aβ1–42-specific polyclonal antiserum of 100µg of total SDS-soluble proteins isolated from Mock-immunized wild type (WT) or from Mock-, SDPM1- or SDPM2-immunized APPswePSEN1(A246E) cortex (APP/PS1). Examples from three different animals are shown per condition. Errors are SEM for n=7–12 animals per condition for n=3 measurements per animal per condition in A–F.
