Cyanine7 azide

Cyanine7 azide is a potent fluorescent dye. Cyanine7 azide can be used for NIR live organism imaging (λex=756 nm, λem=779 nm) . Cyanine7 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[1].
