Differential regulation of membrane potential and conductance via intra-and extracellular pH in fused proximal tubular cells of frog kidney


Intracellular pH (pH i ), membrane potential (V m ) and membrane conductance (G m ) in fused proximal tubular cells of the frog kidney, were determined at three extracellular pH (pH o ) values, 7.5, 8.5 and 6.5. Imposed changes of pH o by ±1 pH unit induced parallel but smaller shifts of pH i . The alkaline milieu hyperpolarized the cells and increased G m… (More)
