Fig. 3.
Interactions of PNP with DOPC BLM in the presence of 10:1 KCl gradient (trans/cis). Low (A) and high (B) amplitude currents induced by 100 μg/ml of COOH-PNP are shown for two applied potentials (+100 and −100 mV in A and +75 and 0 mV in B). Currents induced by 50 μg/ml amidine-PNP (C) are shown for different applied potentials between −50 and +100 mV.
