Figure 7. — State-independent block of BK channels by BP in Rb⁺ solutions. Pooled data. Voltage dependence of BK channel activation (■) and fraction of channels not blocked by 2 µM BP (○) in 100 µM Ca²⁺. Mean values from four experiments shown with standard error limits if larger than symbol. (Inset) Voltage dependence of the time constant of deactivation in the absence (■) and presence (○) of the BP. Mean values from three experiments shown with standard error limits if larger than symbol.
