Carbonic anhydrase II-deficient mice offer a possibility to study the localization along the nephron of membrane-associated carbonic anhydrase (CA) activity without interference from the cytoplasmic enzyme. We studied the localization of CA in kidneys from CA II-deficient and control mice by immunocytochemistry (CA II) and histochemistry. Cytoplasmic staining was found in convoluted proximal tubule, thick limb of Henle, and principal and intercalated cells of collecting duct in the control animals but was absent in the CA II-deficient mice. In cells with cytoplasmic staining the cell nuclei were stained. Intense histochemical activity was associated with apical and basolateral membranes of convoluted proximal tubule, first part of thin limb, thick limb, and basolateral membranes of late distal tubule. In collecting ducts of control animals, the basolateral cell membranes of intercalated cells were the only clearly stained membranes. In CA II-deficient animals one type of intercalated cell was stained most intensely at the apical membranes and another only at the basolateral. We suggest that the former corresponds to Type A intercalated cells secreting H+ ions to the luminal side and the latter to Type B cells secreting H+ ions to the basolateral side.
