ATT 594 alkyne is a bright orange-red fluorescent dye functionalized with a terminal alkyne group for copper-catalyzed azide—alkyne cycloaddition (CuAAC) reactions. The dye enables efficient and selective labeling of azide-modified biomolecules, including proteins, nucleic acids, glycans, and other biologically relevant targets.

The fluorophore exhibits high fluorescence intensity and good photostability, making it suitable for fluorescence microscopy, flow cytometry, and imaging applications requiring sensitive detection, such as super-resolution microscopy and single-molecule detection.
