At least two configurations of intercalated cells, type A and type B, are present in the cortical
collecting duct. Intercalated cells are rich in carbonic anhydrase. However, it is not known
whether there are differences in the level and subcellular distribution of this enzyme
between type A and type B intercalated cells. The purpose of this study was to determine the
relative content and intracellular distribution of carbonic anhydrase II in the various
subpopulations of intercalated cells in the rat collecting duct. A rabbit polyclonal antibody …
