Identification and regulation of K + and Cl − channels in human parotid acinar cells

The properties of K + channels in these cells were studied using patch-clamp methods. Two channels, with conductances of 165±13 pS ( n=6) and 30±1 pS ( n=3), were identified in single-channel experiments. In cell-attached patches the reversal potentials were −67±8 and −74±2 mV for the large and smal...
