7-Hydroxy-4-methylcoumarin-3-acetic acid, SE is an activated, amine-reactive, blue-fluorescent dye for the synthesis of blue-fluorescent biomolecules. The SE activated ester is reactive with primary amines on peptides, proteins, modified nucleotides, biopolymers and other amine-containing biomolecules. Conjugates of 7-Hydroxy-4-methylcoumarin-3-acetic acid, SE have a pH-dependent and environmentally sensitive fluorescence. 7-Hydroxy-4-methylcoumarin-3-acetic acid, SE is a short-wavelength fluorophore that is excited near 363 nm with emission near 455 nm. .
