DBCO-PEG4-hydrazone-NHS is a cleavable heterobifunctional linker containing a DBCO moiety  for click chemistry and a NHS activated ester. The dibenzocyclooctyne group (DBCO) is thermally stable with high specific reactivity toward azide group through strain-promoted click reaction in the absence of a catalyst.

Excellent biocompatibility – strain-promoted click reaction occurs rapidly under mild buffer conditions with no need of accessory toxic copper catalyst

High chemoselectivity – azides and DBCO groups do not react or interfere with other functional groups found in biological samples but conjugate to one another with high efficiency

Hydrophilic PEG4 Spacer – reduces aggregation, minimizes steric hindrance, and enhances solubility

Cleavable hydrazone linker – can be cleaved under acidic condition
