Fig. 4
An example of the microscopic SV current traces at selected voltages. Single channel openings in the control bath (a) (control at 0 time and 5 min later, see explanation in Fig. 2) and in the presence of IAA at 1 μM (b) (the current in the presence of IAA was recorded 5 min after the control at 0 time) are shown. Single channel fluctuations were recorded at + 60, + 80 and + 100 mV. The solid line indicates closed state of the channels, the dashed line – open state. The values of open probabilities for single traces are presented as Po
