sections in a 1.5 ml micro centrifuge tube containing 1 ml of Citrate Buffer solution and placing in a pre-heated temperature block set at 100°C. Tissue was heated for 10 min at 100°C then removed and allowed to come to room temperature for 20 min before washing with PBS 3 times for 5 min and then proceeding with blocking step. For AD mouse brain staining of amyloid plaques, floating sections were placed in 1X Amylo-Glo ® RTD™ (Biosensis) staining solution for 10 min at room temperature without shaking. After staining, sections were washed in PBS 3 times for 5 minutes each and briefly rinsed in MiliQ DI water before being placed back in to PBS followed by blocking. Primary antibodies were added to staining solution (1X PBS, 0.2% Triton X-100, and 1% goat serum) at appropriate dilutions (see below) and incubated overnight at 4°C with slight shaking. The next day, sections were washed 3 times with PBS and stained with Alexa Fluor® conjugated secondary antibodies at 1:400 for 1 h at room temperature with slight shaking in the dark. After secondary staining, sections were washed in PBS 3 times for 5 min and mounted on glass slides. After mounting, slides
