Cy3-PEG-N3 (MW 3400)

Cy3-PEG-N3 (MW 3400) is a Cy3 -azide fluorescent dye used to label for protein and nucleic acid. Cy3-PEG-N3 (MW 3400) 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.
