TCO-PEG-TCO, MW 5,000 is a tetrazine reactive PEG polymer forming a stable dihydropyridazine bond. TCO-Tz ligation is a bioorthogonal reaction which has high selectivity and exceptional kinetics. Bioconjugations are often constrained by the low concentration of biomolecule; thus, a highly reactive TCO-Tz ligation is a very promising technique for this application. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
