4-Di2-ASP is a cationic, orange-fluorescent dye for staining the functioning mitochondria of live cells and for staining presynaptic nerve terminals independently of neuron activity. The fluorescence of this dye is environmentally dependent and is greatly enhanced when the dye is incorporated into membranes or bound to lipophilic molecules. 4-Di2-ASP is non-toxic and has been used to stain neurons in living organisms. This dye also has an unusually large Stokes shift, which may be useful in multicolor imaging. 4-Di2-ASP is excited near 488 nm with fluorescence emission near 608 nm.
