Cyanine 5 azide

Cyanine 3.5 azide is a cyanine dye functionalized with an azide. Cyanine 3.5 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 (Ex/Em = 633/670 nm) .
