AF568 is a synthetic fluorophore. The excitation peak of AF568 lies at 572 nm and its emission peak is at 598 nm. It can be excited using a 561 nm laser. AF568 is spectrally similar to  TF4 (Tide Fluor™ 4), and sulfo-Cyanine3.5 dyes.

As AF568 NHS Ester can be conjugated with proteins and peptides, it is recommended for stable signal generation in imaging, including Western Blotting, fluorescence microscopy, and flow cytometry.
