dslo KCa channels are not modulated by redox reagents. Currents were elicited from a HEK293 cell line stably expressing Drosophila dslo channels (splice variant A1/C2/E1/G3/I0) (Adelman et al., 1992) as described in Figure 1.A, Current families evoked by command voltage steps ranging from −80 mV to +70 mV from a holding potential of −80 mV.B, The time dependence of dslo V0.5 changes after patch excision, the addition of 5 mm DTT (t = 25 min), and the washout of this agent (t = 45 min). C, The time dependence of macroscopic conductance values (solid circles) and the slope of the voltage dependence (open circles) after excision and DTT treatment.
