DABCYL C2 maleimide is the thiol-reactive form of DABCYL, and widely used to prepare a variety of FRET-based probes that contain DABCYL. DABCYL is one of the most popular acceptors for developing FRET-based nucleic acid probes and protease substrates. It is often paired with EDANS or a blue fluorescent donor such as coumarin dyes.
