Effect of extracellular ACA (ACAe) on BK channel open probability (Po) compared to control conditions (con) at 1.2 μM [Ca²⁺]i and after wash out (w. o.).

[ACA]e	Po con	Po ACAe	Po w. o.
300 μM (n = 7)	0.056 ± 0.015	0.059 ± 0.017	0.060 ± 0.020
1 mM (n = 9)	0.046 ± 0.017	0.048 ± 0.019	0.041 ± 0.010
3 mM (n = 6)	0.039 ± 0.005	0.043 ± 0.005	0.041 ± 0.005
10 mM (n = 6)	0.079 ± 0.043	0.072 ± 0.039	0.066 ± 0.035

Extracellular ACA in different concentrations ([ACA]e) did not affect BK channel open probability.
