5(6)-FAM PEG3 alkyne (protected) Size:10mg 322 SMILES OC(=O)CCCOC1=C2C(=O)N(C3CCC(=O)NC3=O)C(=O)C2=CC=C1 Purity (HPLC)The water soluble 5(6) FAM PEG3 alkyne (protected) 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 alkyne (protected) is an excellent azide reactive fluorescent reagent for labeling alkyne containing biological molecules through click chemistry.
