  1. The membranes were formed of 1% DiphPC/n-decane. The aqueous solutions were unbuffered and had a pH of about 6 if not indicated otherwise. The applied voltage was 20 mV and the temperature 20 °C. The single values represent the means (± SD) of at least 100 single-channel events derived from at least four individual membranes
