Synonyms: 5-(and -6) ? carboxyfluorescein PEG3 azide (protected)

Functional Activity:
The water soluble 5(6)-FAM PEG3 azide (protected) has a long PEG3 spacer that separates the dye carboxyfluorescein (commonly known as FAM) from the terminal azide group. The water-soluble PEG3 spacer should minimize the interaction between the dye and the biomolecule to be labeled. 5(6)-FAM PEG3 azide (protected) is an excellent alkyne-reactive fluorescent reagent for labeling azide-containing biological molecules through click chemistry.
