Pyronin G as a fluorescent probe for quantitative determination of the membrane potential of mitochondria.

T C Tomov.   

Abstract

Added to mitochondrial suspension, pyronin G changes the intensity of its fluorescence depending on the membrane potential (energy state) of the mitochondria. The mechanism of this effect is studied and a dependence is obtained between the membrane potential and the fluorescence intensity. This permits quantitative determination of the membrane potential by the changes in the fluorescence of the suspension. A method is proposed for measuring the membrane potential of vesicles in the -120 to -220 mV interval.
