DBCO-PEG6-NHS ester is a bifunctional linker with dibenzocyclooctyne (DBCO) and NHS ester groups flanking PEG6 (hexaethylene glycol). The PEG spacer increases solubility in aqueous media and provides a long and flexible connection that minimizes steric hindrance involved with ligation.

Dibenzocyclooctyne readily reacts with azides via copper-free click chemistry reaction (strain-promoted alkyne azide cycloaddition, SPAAC). DBCO is one of the most reactive cycloalkynes that does not react with tetrazines.

The amine-reactive N-hydroxysuccinimide residue provides easy attachment to almost any primary or secondary amine group, such as protein, peptide, or small molecule amine.
