Table 3. The mean ratios (I_∞/I_∞⁰) of steady-state transmembrane currents induced by AmB in the presence (I_∞) and absence (I_∞⁰) of modifiers in bilayers composed of PC:Stigm (67∶33 mol%) and PC:DhChol (67∶33 mol%).

membrane composition	phloretin	RH 421
PC:Stigm	5.3±3.1	1.1±0.1
PC:DhChol	1.7±0.3	1.2±0.1

The membranes were bathed in 2.0 M KCl, pH 7.0.
