Cyanine 3.5 azide

Cyanine 3.5 azide is a functionalized cyanine dye with an azide group. As a click chemistry reagent, it contains an azide moiety that can engage in copper-catalyzed azide-alkyne cycloaddition (CuAAc) reactions with molecules bearing alkyne groups. Additionally, it can participate in strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules possessing DBCO or BCN groups. [Excitation/emission wavelengths = 591/604 nm].
