Select sections to process from the brain tissue bank.
Wash sections thoroughly with a phosphate-buffered saline(PBS, 0.01 Molarity (M) , 7.4 ) solution.
Treat the sections at Room temperature with a 1% sodium borohydride (NaBH4) solution in PBS for 00:20:00 .
20m
Rinse sections thoroughly in PBS.
Pre-incubate sections for 01:00:00 at Room temperature in a solution containing 1% normal serum (from the species used to generate the secondary antibodies), 0.3% Triton X-100, and 1% bovine serum albumin (BSA) in PBS.
1h
Incubate the sections for 24:00:00 at Room temperature in a solution containing the primary antibodies in 1% normal serum, 0.3% Triton X-100, and 1% BSA in PBS.
1d
Next day, thoroughly rinse the sections in PBS.
Incubate the sections in a PBS solution containing the appropriate biotinylated secondary antibody (1:200; Vector Labs, Burlingame, CA, USA) combined with 1% normal serum, 0.3% Triton X-100, and 1% BSA for 01:30:00 at Room temperature .
1h 30m
Wash the sections in PBS.
Incubate the sections in an avidin-biotin-peroxidase complex (ABC; 1:100; Vector Labs, Burlingame, CA, USA) solution for 01:30:00 at Room temperature .
1h 30m
Rinse the sections in PBS twice followed by a third rinse in TRIS buffer (0.05 Molarity (M) ; 7.6 ).
Incubate the sections in a solution containing 0.025% 3,3ʹ-diaminobenzidine tetrahydrochloride, 10 millimolar (mM) imidazole, and 0.005% hydrogen peroxide in Tris buffer for 00:10:00 at Room temperature .
10m
Rinse the sections with PBS.
Mount sections onto gelatin-coated slides, and coverslip with Permount.
Digitalize the slides with an Aperio ScanScope CS system (Aperio Technologies).
