Cyanine3 DBCO is a copper-free click chemistry reagent designed for rapid, bioorthogonal conjugation with azide-containing molecules via strain-promoted azide-alkyne cycloaddition (SPAAC). This non-sulfonated derivative eliminates the need for cytotoxic copper catalysts, making it ideal for sensitive biological applications such as live-cell imaging, in vivo labeling, and protein modification.
The DBCO (dibenzocyclooctyne) group ensures fast reaction kinetics with azides while maintaining Cy3's excellent photostability and brightness. For enhanced water solubility in physiological conditions, sulfo-Cyanine3 DBCO is recommended.
