Fig. 2. Comparison of ClC-2 and H⁺-K⁺-ATPase distribution in mouse colon. (a,c) Consecutive sections stained with anti-ClC-2 and anti-H⁺-K⁺-ATPase respectively. (b,d) Higher magnifications of the portions identified by the boxes in a and c are shown. Arrows in b indicate surface epithelial cell-to-cell junctions and the bottom of a surface cell. Bars: a and c, 25 µm; b and d, 10 µm.
