Fig. 5.
Reversal potentials assessed from I-V relationships due to amidine-PNP interactions with BLM as a function of BLM surface charge under 10:1 (trans/cis) KCl gradient. Currents were recorded as voltage was increased continuously over a period of 15 s from −100 to +100 mV. Arrow indicates the corresponding reversal potential for each I-V relationship. Dotted lines indicate zero current.
