Western blots of enamel organ extracts from Slc26a-null mice stained with anti-Dra, anti-Slc26a6, or anti-pendrin to detect up- or downregulation of isoforms of the Slc26a family. Top row from left to right: enamel organ extracts from Dra-, Ae2-, and Cftr-null mice stained with anti-Slc26a6. The bar graphs in the second row represent the density measurements. Third row: extracts from Slc26a6-, Ae2-, and Slc26a6-null mice stained with anti-Dra (Slc26a6 and Ae2) or anti-pendrin. Fourth row represents density measurements. The table at the bottom presents a summary of the changes. WT, wild type.
