6-FAM-PEG3-Azide

6-FAM-PEG3-Azide is a fluorescent dye that can be used to label oligonucleotide. 6-FAM-PEG3-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.
