5(6)-FAM PEG3 azide fluorescein 92 SMILES: CC1(C)\C(=C/C=C/C2=[N+](CCCCCC(=O)NCC#C)C3=CC=C(C=C3C2(C)C)S(O)(=O)=O)N(CCCS([O-])(=O)=O)C2=CC=C(C=C12)S(O)(=O)=O Purity (HPLC):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 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 is an excellent alkyne reactive fluorescent reagent for labeling alkyne containing biological molecules through click chemistry.
