Figure 7. — Representative open dwell-time distributions at different cytoplasmic pH and [Ca²⁺]. Smooth curves represent fits of these data with a single-exponential component with the indicated time constant (τ). Distributions from bilayers containing more than one active channel (n > 1) were generated from data that showed only a single open current level. The number of fitted intervals in the distribution were: pH 6.5, 5 mM, 84 events; pH 6.5, 10 mM, 4,024 events; pH 6.5, 30 mM, 5,695 events; pH 7.3, 2 mM, 231 events; pH 7.3, 3 mM, 2,451 events; pH 7.3, 30 mM, 5,527 events; pH 8.1, 0.7 mM, 1,203 events; pH 8.1, 1 mM, 2,570 events; pH 8.1, 10 mM, 7,386 events.
