Mouse brain samples for immunofluorescent staining were prepared as previously reported [20 (link), 21 (link)]. Sections for staining were incubated with the following primary antibodies: rabbit anti Iba1 (1:2000, Wako) and mouse anti-Aβ (6E10, 1:1000, Covance) at 4 °C overnight. After being washing with PBS, the sections were incubated with donkey anti-rabbit Alexa 488 (1:500; Jackson ImmunoResearch) and donkey anti-mouse Cy3 (1:500; Jackson ImmunoResearch) at 4 °C for 2 h. After further washing, the sections were mounted in Vectashield anti-fading medium (Vector Laboratories). The fluorescence images were observed using a confocal laser scanning microscope (CLSM; C2si, Nikon).
