Serial, coronal frozen sections were immunostained for GFAP and Iba1 as described earlier.
46 (link) Sections were treated with 3% hydrogen peroxide to reduce the endogenous peroxidase activity. The sections were then incubated with
polyclonal rabbit anti-GFAP (1:100, Dako, Denmark) or
polyclonal rabbit anti-Iba-1 (1:500, Abcam, Cambridge, MA, USA) antibodies overnight at 4°C. The sections were incubated with
biotinylated anti-rabbit IgG (1:20, Vector Labs, Burlingame, CA, USA) for 1 h, followed by incubation with
ExtrAvidin peroxidase (1:20, Sigma Chemicals, St. Louis, USA) for another 1 h. The color was developed using
DAB (Vector Labs, Burlingame, CA, USA) as chromogen. Sections were mounted on gelatin-coated slides, air dried, dehydrated in ethyl alcohol, cleared in xylene, and mounted with DPX. All the brain sections were examined and immunostained cells were counted by Olympus BX51 TF upright transmitted light microscope using 40× objective (aperture is 0.75).
