Ca2+ dependence of sulphatide induced increase in Po of the channel. Current traces showing effect of sulphatide on the BKCa channels at various concentrations of [Ca2+]i in the bath before (a) and during exposure to 10 μM sulphatide (b) at a holding potential of +10 mV. (c) Statistics of the data (n=3–24). Solid line is the best fit to the Hill equation (see text).
