Immunofluorescence staining of GLUT9 in PFA-fixed murine brain sections. Frozen sections of paraformaldehyde-fixed wild-type murine brain were used for immunofluorescence staining. a, b Antigen absorption test. Immunofluorescence staining of the ependymal wall of the dorsal third ventricle using a anti-GLUT9 antibody and b antigen-preabsorbed antibody. Scale bar 100 µm. c, d Immunofluorescence staining of GLUT9 (magenta), acetylated-tubulin (Ac-Tubulin, green) and DAPI (blue) on ependymal cells. Scale bar 10 µm. e–g Immunofluorescence staining of GLUT9 (magenta) and NeuN (green) showing co-localization in neurons. Scale bar 10 µm. D3V, dorsal third ventricle; DAPI, 4′,6-diamidino-2-phenylindole; NeuN, neuronal nucleus marker
