Figure 2.

Effects of diazoxide (Dzx) on L-type Ca²⁺ currents are prevented by ROS scavengers. A, experimental protocol. B, I-V plots showing mean ± SE of peak L-type currents after 55 min in NAC (4 mM; n = 18) and after incubation in NAC plus diazoxide (100 µM; n = 23), as in A. Insets show representative L-type Ca²⁺ currents during pulses to +10 mV, under conditions as in A. Calibration bars are 20 ms and 2 pA·pF⁻¹.
