1,1,1-Trifluoroethyl-PEG3-Propargyl

1,1,1-Trifluoroethyl-PEG3-Propargyl is a heterobifunctional reagent with an alkyne group and a trifluoroethyl group. The alkyne group reacts with azide compounds or biomolecules in copper catalyzed Click Chemistry to form a stable triazole linkage. The trifluoroethyl group is used to react with lysine and other primary amine groups in proteins, antibody and other molecules and surfaces.
