Application: Maleimide functionalized cyclooctyne derivative for incorporation of the cyclooctyne moiety into thiol containing compounds or biomolecules. Cyclooctynes are useful in strain-promoted copper-free azide-alkyne cycloaddition reactions. This dibenzocyclooctyne will react with azide functionalized compounds or biomolecules without the need for a Cu(I) catalyst to result in a stable triazole linkage.

Applications Include:
• Protein-peptide conjugates
• Antibody-enzyme or antibody-drug conjugates
• Protein or peptide-oligonucleotide conjugates
• Surface modification
