Biological Activity for 3-Azido-7-hydroxycoumarin

Key information: 3-Azido-7-hydroxycoumarin is a water-soluble fluorogenic fluorescent dye. Supplied with an azide reactive handle for click chemistry. It emits intense fluorescence only after 'click' reaction when it forms triazoles at the site of alkyne modified biomolecules. Suitable for live-cell imaging.

Application: Fluorescence microscopy. Can be used to label DNA in proliferating cells following 5-Ethynyl-2'-deoxyuridine (Cat.No. 7207) incorporation. Cell permeable.

Properties and Photophysical Data: Excitation and emission maxima (λ) are 404 nm and 477 nm, respectively, after click reaction.
