YO-Pro 1, a cyanine dye consisting of benzoxazole and quinoline rings connected by a linker, is almost nonfluorescent in water, but its fluorescence is greatly enhanced after intercalation in double-stranded DNA, forming the basis of DNA concentration assays. Ex/Em (bound DNA) = 491/509 nm. YO-Pro 1 can be used to identify apoptotic cells.
