1,6-Diphenyl-1,3,5-hexatriene
1,6-Diphenyl-1,3,5-hexatriene (DPH, excitation/emission=350 nm/420 nm) is almost non-fluorescent in water, but it exhibits a strong increase in fluorescence after intercalation into membranes and can be used as a probe for viscosity, polarity and lipid order.

7-AAD
7-AAD is a fluorescent DNA intercalator, which upon binding to dsDNA can be excited by the argon-ion laser and emits at 647 nm (1-3). 7-AAD binds selectively to GC regions of DNA, which makes the dye useful for chromosome banding studies (4).
