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