AF 568 is a synthetic fluorophore. The excitation peak of AF 568 lies at 572 nm and its emission peak is at 598 nm. It can be excited using a 561 nm laser. AF 568 is spectrally similar to TF4 (Tide Fluor™ 4), and sulfo-Cyanine3.5 dyes.
As AF 568 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.
