Dosing the electrochemical membrane potential. Inside/outside K+ concentrations were set to 20 μM/200 mM K+ (A), 200 μM/200 mM K+ (B), 2 mM/200 mM K+μM (C), and 40 mM/200 mM K+ (D). From the apparent oxonol VI fluorescence and the calculated Nernst potential, Δψ was determined as −240 mV (A), −177 mV (B), and 74−50 mV (C).
