$Figure 4. State-independent block of BK channels by TBA in Rb+ solutions. Pooled data. Voltage dependence of BK channel activation (■) and fraction of channels not blocked by TBA (○) in 100 µM Ca2+. Mean data shown with standard error limits if larger than symbol. Data from six to nine experiments, except n = 3 at −90 mV.$
