Description
Oxazole yellow is a cyanine dye composed of benzoxazole and quinoline rings connected by a linker. It is almost non-luminescent in water, but its green fluorescence is significantly enhanced after intercalation in double-stranded DNA. Oxazole yellow can be used to detect cell apoptosis[1][2][3].
