BODIPY™ FL (4,4-Difluoro-5,7-Dimethyl-4-Bora-3a,4a-Diaza-s-Indacene-3-Propionic Acid) (Invitrogen™)

The amine-reactive BODIPY™ FL propionic acid can be used to create green-fluorescent bioconjugates following carbodiimide-activation of the carboxylic acid on the dye and reaction with amines. The electronically neutral BODIPY™ FL dye has the most fluorescein-like spectra of the green-fluorescent BODIPY™ dyes.
