DABCYL标记说明
4-(4-二甲氨基苯基偶氮)苯甲酰基（Dabcyl）是一种发色团，常与荧光团（如EDANS）结合用作猝灭剂。Dabcyl/EDANS FRET（荧光共振能量转移）对的福斯特半径为3.3纳米。
4-(4-Dimethylaminophenylazo)benzoyl (Dabcyl) is a chromophor often used as a quencher in conjunction with a fluorophore (e.g., EDANS). Dabcyl/EDANS FRET pair have a Forster radius of 3.3 nm.

Glossary: EDANS
5-[(2-Aminoethyl)amino]naphthalene-1-sulfonyl (EDANS) is fluorophor with an excitation at 340 nm ▉ and emission of 490 nm ▉. EDANS is often paired together with acceptors like dabcyl for FRET experiements.
