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. The probe is particularly useful for preparing fluorescent drug or ligand analogs that bind to hydrophobic sites in proteins, membranes or other biological receptors. Wavelength Maxima: Excitation 372nm
