DiBAC4(3)
DiBAC4(3) (Bis-(1,3-Dibarbituric acid)-trimethine oxanol) is a so-called translational membrane potential dye that redistributes within the cell membrane when membrane potential changes (1,2). The fluorescence of the dye is enhanced when the dye enters the cell membrane as a result of membrane depolarization.

DiIC1(5) (1,1′-dimethyl-3,3,3′,3′-tetramethylindodicarbocyanine, iodide)
The carbocyanine dye DiIC1(5) has been used to measure mitochondrial membrane potential in apoptotic cells. Loss of membrane potential in apoptotic cells is reflected by a decrease of fluorescence signal in the infrared channel.

DiO/DPA Membrane Potential Detection Kit
The DiO/DPA system detects cytoplasmic membrane potential changes using the principle of fluorescence resonance energy transfer (FRET), where DiO is a “stationary” FRET donor while DPA acts as a potentiometric FRET acceptor. The DiO/DPA system has been reported to produce a fluorescence signal change of >56% in HEK-293 cells and >25% in neuronal cultures and brain slices per 100 mV membrane potential change.
