ATP Permeability of Large-Conductance Anion Channel in the Presence of Different Cations in the Pipette Solution

Pipette solution Erev PATP/PCl n
Ringer −16.2 ± 1.9 0.096 ± 0.014 5
Cs-Ringer −18.2 ± 1.0 0.085 ± 0.006 6
TEA-Ringer −18.7 ± 1.5 0.083 ± 0.009 5

Reversal potentials obtained from ramp I-V curves after correction for the background currents. The mean values are not significantly different based on t test at P . 0.05. PATP/PCl was calculated using .
