TCO-PEG4-NHS Ester is a pegylated lebeling reagent with enhanced solubility in aqueous buffers used for TCO labeling of antibodies, proteins and other primary amine-containing macromolecules. A long, hydrophilic PEG4 spacer arm provides a long and flexible connection that minimizes steric hindrance involved with ligation to complementary tetrazine-containing molecules.
