A different kind of hemocyanin channel in oxidized cholesterol membranes

Abstract A new kind of hemocyanin channel in oxidized cholesterol black lipid membranes has been characterized using the protein extracted from the mollusc Paludina Vivipara. The channel has constant conductance versus applied voltage and is subjected to open-closed fluctuations that follow fairly well a binomial distribution, independent from the applied potential. Single channel electrical properties are in good agreement with those of many channels membranes. This channel is completely different from that already studied formed by Keyhole Limpet Hemocyanin and for some aspects reminds other channels particularly those obtained with Excitability Inducing Material and Alamethicin.
