Figure 1.
Rundown of whole-cell currents in COSWT (A–C) and COSphox (D–F) cells. Families of currents were recorded at various times after establishing whole cell configuration at pHi 5.5 and pHo 7.0 in TMAMeSO3 solutions. Insets illustrate the voltage pulses, which were applied at an interval of 15 s. Results are representative of 6 COSWT cells and 22 COSphox cells. The current at the holding potential decreased progressively during most of the families of pulses illustrated.
