AF 568 is a fluorescent dye with excitation peak at 572 nm and emission peak at 598 nm. AF 568 azide is a photochemically stable, specific, and highly efficient tool for labeling biomolecules. It is water soluble and insensitive to pH changes between pH 4 and pH 10. The reaction conditions do not require high temperature or pressure.

Labeling with AF 568 azide via click chemistry is a powerful technique for the production of bioconjugates. AF 568 azide is an excellent tool for imaging purposes, including fluorescent microscopy and flow cytometry, where label brightness and photostability are essential.
