TCO-PEG4-maleimide is a click chemistry building block containing a TCO moiety and a maleimide group. The maleimide group will react with a thiol group to form a covalent bond. TCO moiety is very reactive with tetrazine (3rd generation click chemistry). Reagent grade, for research purpose. 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.
