AF 568 is a fluorescent dye with excitation maximum at 572 nm and emission maximum at 598 nm. This dye has better photostability than traditional fluorescent stains (fluorescein isothiocyanate FITC, phycoerythrin PE etc.).

AF 568 carboxylic acid is a non-reactive form of AF 568 dye that can be used as a reference standard in experiments involving AF 568 dye conjugates. Besides, the carboxylic group can react with hydrazines, hydroxylamines, and amines using carbodiimides such as EDAC.
