Tetrazine-PEG4-Maleimide is a mid-length, sulfhydryl-reactive labeling reagent with enhanced water-solubility provided by a PEG4 spacer.
Tetrazine-PEG4-Maleimide enables simple and efficient incorporation of a tetrazine moiety onto antibodies, cysteine-containing peptides and other thiol-containing molecules. 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 complementary TCO-containing molecules.
