The excitation maximum of AF568 lies at 572 nm and its emission maximum is at 598 nm. AF568 has excellent photochemical stability and brightness.

AF568 alkyne derivate is an effective tool for labeling purposes. It is easily detected in the ROX channel with a high signal-to-noise ratio in different biological samples. Besides, AF568 alkyne is water soluble and insensitive to pH changes between pH 4 and pH 10. Mild reaction conditions are suitable for most biomolecules, cells, and tissues.

Bioconjugation with AF568 alkyne presents a powerful technique for the production of fluorescently labeled biomolecules. AF568 alkyne is recommended for visualization procedures, including fluorescence microscopy, flow cytometry, and other applications where label brightness and photostability are required.
