- Description
TCO-PEG3-NHS ester combines a TCO moiety with an amine-reactive NHS ester through a hydrophilic PEG spacer. It is used to introduce TCO groups onto antibodies, proteins, and other macromolecules bearing primary amines. The spacer increases water solubility and reduces steric hindrance during ligation, supporting its use as a PEG linker in click chemistry workflows.
Listed solvents are DMSO, DCM, DMF, and the specified storage temperature is -20°C. TCO can isomerize to CCO with loss of reactivity; long-term storage is not recommended.
