Immunohistochemical localization of HNF4α in rat tissues. Frozen sections (C and F) and paraffin sections (A, B, D-E, G-I) were stained with HNF4α K9218 antibody. A positive reaction (brown colour) is seen in the nucleus of hepatocytes in the liver (A and D), mucosal epithelial cells of the small intestine (B and E) and colon (G), and the proximal tubules of the kidney (C and F). Epithelial cells of the stomach (H), pancreas (I), glomerulus, distal tubules, and collecting tubules of the kidney are negative. Paraffin sections show the same staining pattern as frozen sections. Original magnification: D, E, F ×400; A, B, C, G, H, I ×200.
