the cell-specific pattern of [ ( 3 ) h ] ouabain binding to principal secretory cells and the membrane-specific localization of binding sites to the nonluminal surfaces of these cells were identical to the distribution of na+-k+-atpase as reflected by the cytochemical localization of ouabain-sensitive and k+-dependent nitrophenyl phosphatase activity .
