3,4-Dibromo-Mal-PEG12-TCO is a PEG linker that includes a TCO function to readily react with tetrazine groups in target compounds and a dibromomaleimide group which allows for two points of substitution due to the two bromine atoms. The PEG12 chain imparts water solubility. 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.
