TCO-PEG4-DBCO is a heterobifunctional click chemistry reagent containing a TCO and a DBCO moiety. TCO group specifically and efficiently reacts with terrahydrazine at fast speed. DBCO is very reactive toward Azide through copper free click chemistry, the PEG spacer increases the aqueous solubility of the reagent. 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.
