AF 488 is a water-soluble green-fluorescent dye with high fluorescence quantum yield and high photostability. The dye is similar to FITC in spectral characteristics (absorption max. at 495 nm, emission max. at 519 nm) and is not sensitive to pH changes within the range from 4 to 10. This reagent is a pure 5-isomer.

This AF 488 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, specific and suitable for in vitro cell labeling.
