N-Succinimidyl 4-[4-(Dimethylamino)phenylazo]benzoate

Synonyms: 4-[4-(Dimethylamino)phenylazo]benzoic Acid N-Succinimidyl Ester, DABCYL N-Succinimidyl Ester

Long wavelength azo quencher is a useful reagent (similar to MANCYL-SE) for labeling proteins or peptides through their amino-groups. The succinimidyl ester is reactive with terminal amines or lysines of peptides and other nucleophiles for labeling studies of proteins.

  • DABCYL NHS ester

DABCYL is a widely use azo quencher that has absorption wavelengths that overlap well with EDANS, and some other fluorophores, in FRET-type quenched substrates. This reactive version of DABCYL has an NHS (N-hydroxysuccinimidyl) group that allows easy labeling of proteins or peptides for use in substrates or other detection systems.
