5(6)-FAM PEG3 azide

5(6)-FAM PEG3 azide

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