Immunohistochemistry of the paraffin section of human brain with E5206. Cortex and subcortical white matter from human parietal lobes was stained with E5206 in the absence (A) or presence (B-H) of antigen retrieval. White matter (C, D), cortex adjacent to a sulcus (E, F), and a region surrounding a sulcus (G, H) stained with either E5206 (C, E, G) or rabbit polyclonal anti-AQP4 C-terminal domain antibody H-80 (D, F, H) are shown magnified (×200).
