EDANS (EDANS acid [5-((2-Aminoethyl)amino)naphthalene-1-sulfonic acid]) is a novel and quenched fluorogenic substrate for assaying retroviral protease by resonance energy transfer (RET).

EDANS sodium (5-(2-Aminoethylamino)-1-naphthalenesulfonic acid sodium salt) is a donor for developing FRET-based nucleic acid probes that is widely used in real time PCR assays.

Dabsyl-Leu-Gly-Gly-Gly-Ala-Edans is a fluorophore-labeled peptide with specificity for assaying the peptidase activity of the LasA protease from Pseudomonas aeruginosa, offering application value [1].

RE (EDANS) EVNLDAEFK (DABCYL) R is a double-labeled peptide with EDANS and DABCYL, functioning as a fluorescent substrate for BACE1 with an emission wavelength of 360 nm and an excitation wavelength of 528 nm. Its utility lies in the quantification of BACE1 activity, with the intensity of fluorescence being directly proportional to enzyme activity levels [1].

DABCYL-Glu-Arg-Nle-Phe-Leu-Ser-Phe-Pro-EDANS is a fluorescent dye utilized as a fluorogenic substrate for aspartyl proteinase from the human malaria parasite [1]. It requires protection from light during storage.
