Effect of manipulation of Cl− concentrations on (Ca2+) inward currents in mitoplasts. a Representative traces of i-MCC channel activity recorded with the use of low Cl− (40 mM Cl−)-containing pipette solution. Test potential is −100 mV. b Amplitude histogram of the channel activity shown in (a). c Representative traces showing the activity of b-MCC at different voltages indicated in the presence of 40 mM bath Cl−. d Corresponding voltage dependency of single-channel amplitudes of single-channel openings shown in (c). e Representative current responses to a voltage ramps from −150 to +150 mV under our standard recording conditions showing the activity of Cl− channels at positive potentials
