Mal-PEG2-bis-PEG3-BCN (exo) is a heterotrifunctional linker containing two BCN moieties for click chemistry and a maleimide group for sulfhydryl ligation. The BCN demonstrates high specific reactivity toward azide group through strain-promoted click reaction in the absence of a catalyst with least hydrophobicity among all cyclooctynes.

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

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

Hydrophilic PEG3 Spacer – reduces aggregation, minimizes steric hindrance, and enhances solubility
