Immunohistochemistry Free-Floating: GFAP Antibody [NBP1-05198] - Staining of a section of mouse hippocampus stained with chicken pAb to GFAP, NBP1-05198, dilution 1:5000 in green and costained with rabbit pAb to FOX3/NeuN, dilution 1:5000, in red. The blue is DAPI staining of nuclear DNA. Following transcardial perfusion with 4% paraformaldehyde, mouse brain was post fixed for 24 hours, cut to 45 uM, and free-floating sections were stained with the above antibodies. The GFAP antibody stains a network of astroglial cells while the Fox3/NeuN antibody stains the nuclei and proximal perikarya of neurons.
