(4E)-TCO-PEG4-amine

TCO-PEG4-Amine enables simple and efficient incorporation of TCO moiety onto antibodies,peptide or other molecules through amide coupling with carboxylic acid group.The hydrophilic polyethylene glycol(PEG)spacer arm imparts water solubility that is transferred to the labeled molecule,thus reducing aggregation of labeled proteins stored in solution.The PEG spacer arm provides a long and flexible connection that minimizes steric hindrance involved with ligation to plementary tetrazine-containing molecules.
