The fluorescence of the dye CC 6 [(3 hexyl 2 (3 hexyl 2 benzoxazolinylidene) 1 propenyl) benzoxazolium iodide] was shown to indicate Donnan potentials in rabbits skeletal muscle myofibrils. These results are in aggreement with previously published work in which the potentials were measured with microelectrodes on glycerol extracted muscle fibers. The magnitude of the Donnan potential of the myofibrils was shown to be dependent on the state (rigor or relaxed) of the system.
