FITC-PEG-N3 (MW 5000)

FITC-PEG-N3 (MW 5000) is an azide fluorescent dye containing polyethylene glycol (PEG) and FITC. FITC-PEG-N3 (MW 5000) 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.
