Dansyl chloride (ultra pure)

Amine reactive dye



ENZ-52455	100 mg	84.00 USD

Dansyl chloride demonstrates amine-specific fluorescence (557 nm emission), enabling environmentally sensitive detection in biophysical studies. Dansyl chloride reacts with both aliphatic and aromatic primary amines to produce a stable blue-green fluorescent sulfonamide adduct. In general, the probe serves as a good acceptor for fluorescence resonance energy transfer (FRET) when tryptophan is used as the donor. Alternatively, the dansyl moiety can serve as the donor and polydiacetylene as the acceptor in liposome studies.
