Fluorescein (FAM) is a popular fluorophore that has bright emission in the green area of visible spectrum. This derivative of fluorescein contains tetrazine moiety. Tetrazines react with trans-cycloalkenes and other strained olefins in a reaction called inverse electron demand Diels-Alder reaction (ied-DA). The reaction is very quick and specific. The reagent contains pure 6-isomer of FAM.
