Effects of COOH-PNP exposure on the cis or trans side of DOPC BLM under a 10:1 (trans/cis) KCl gradient. (A) I-V plot obtained from analysis of currents resulting from protocol described in Fig. 3C. (□) denotes PNP on cis side; (○) denotes COOH-PNP on trans side. (B) Average reversal potentials assessed from I-V relationships due to COOH-PNP on cis or trans side of BLM.
