Current fluctuations corresponding opening and closing of the single AmB-channels in the planar lipid bilayers.

<p>The membranes were made from the PC∶Chol (67∶33 mol%) and bathed in 2 M KCl 5 mM Hepes pH 7.0. <i>V</i> = 200 mV. Bilayer bathing solutions contain: (<b>A</b>) – 20 µM phloretin, (<b>B</b>) – no dipole modifiers, (<b>C</b>) – 5 µM RH 421, (<b>D</b>) – 20 µM quercetin, (<b>E</b>) – 5 µkM RH 160, (<b>F</b>) – 5 µM RH 237.
