ATTO 488 azide

ATTO 488 azide is an azide derivative of ATTO 488 with excitation/emission maxima at 500/520 nm. ATTO 488 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.
