DBCO-PEG-TCO, MW 5,000 is a polyPEG reagent containing TCO, which is a click chemistry handle that readily reacts with tetrazine groups on a target molecule, and DBCO, which is a click chemistry handle that readily reacts with azide groups without the need for copper. The 5k PEG polymer greatly improves the solubility of the compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries. The half-life of TCO is short as it will naturally isomerize into CCO (cis-cycloctene) and lose the reactivity. TCO compound is not recommended for long term storage.
