Janelia Fluor® 646, Azide

Janelia Fluor 646, Azide (JF646, Azide) is a red fluorogenic fluorescent dye containing a click chemistry group Azide. Janelia Fluor 646, Azide can be used for live-cell imaging experiments[1][2]. Janelia Fluor products are licensed under U.S. Pat. Nos. 9,933,417, 10,018,624 and 10,161,932 and other patents from Howard Hughes Medical Institute. Janelia Fluor? 646, Azide is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
