Averaged and normalized Ig of WT hERG1 channels measured using p/−8 leak and capacitance current subtraction. (A) Ig in response to test voltages Vt of −60, −30, …+60 mV during 0–300 ms. The membrane voltage is clamped to −110 mV otherwise. (B and C) IgON at 0–10 ms and 10–300 ms, respectively. (D and E) IgOFF at 300–310 ms and 310–600 ms, respectively.
