TCO-PEG4-TFP Ester is an amine-reactive labeling reagent used to modify proteins, antibodies, and other amine-containing biopolymers. A 2,3,5,6-tetrafluorophenol (TFP) is a reactive ester that displays much better stability toward hydrolysis in aqueous media resulting in more efficiency and better reproducible labeling of biopolymers. TFP ester of carboxylic acids react with primary amines at the same rate as NHS ester forming covalent amide bond that is identical to one formed by the reaction between primary amines and NHS esters or sulfo-NHS esters.
