TCO-PEG36-acid is a long chain, monodisperse PEG reagent with a TCO function group. The terminal carboxylic acid can react with primary amine groups in the presence o EDC to form an amide bond. This reagent can react with tetrazine-containing compounds without the catalysis of Cu or elevated temperatures. 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.
