Mal-bis-PEG3-DBCO is a heterotrifunctional linker containing two DBCO moieties for click chemistry and a maleimide group for sulfhydryl conjugation. 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 PEG Spacer – reduces aggregation, minimizes steric hindrance, and enhances solubility
