dabcyl

Dabcyl acid (DABCYL) is the original dark fluorescence quencher.

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.

Dabcyl acid, SE (Dabcyl, SE) is the amino-reactive form of Dabcyl acid and used to prepare a variety of FRET-based probes that contain Dabcyl acid.

Dabcyl acid sodium (DABCYL sodium), a nonfluorescent chromophore and quencher, serves as a molecular beacon in nucleic acid probes for the detection and identification of specific nucleic acids in homogeneous solutions [1] [2].

DABCYL-Glu-Arg-Nle-Phe-Leu-Ser-Phe-Pro-EDANS is a fluorescent dye used as a fluorogenic substrate for aspartyl proteinase from the human malaria parasite [1]. It should be stored protected from light.

RE (EDANS) EVNLDAEFK (DABCYL) R is a double-labeled peptide with EDANS and DABCYL, serving as a fluorescent substrate for BACE1 with an excitation wavelength of 360 nm and an emission wavelength of 528 nm. It is used to quantify BACE1 activity, with fluorescence intensity proportional to enzyme activity levels [1].
