Di-8-ANEPPS is a potentiometric fluorescent dye that noninvasively measures transmembrane voltage. Initially non-fluorescent, it becomes strongly fluorescent when bound to the lipid bilayer of cell membranes (with an excitation/emission max of approximately 467/631 nm). The fluorescence intensity of Di-8-ANEPPS varies proportionally with changes in transmembrane voltage.
