Figure 4. Titration of the P66-induced membrane conductance with PEG 600 (A) and maltohexaose (B).

The membrane was formed with PC/n-decane. The aqueous phase contained ∼100 ng ml⁻¹ P66, 1 M KCl and respective nonelectrolytes in the concentration as indicated; temperature = 20°C; applied voltage = 20 mV.
