Description

Application

Dibenzocyclooctyne-PEG4-N-hydroxysuccinimidyl ester may be used in the synthesis of a prostate-specific membrane antigen (PSMA)-targeted single photon emission computed tomography (SPECT) agent via copper-less click chemistry.

Succinimidyl ester (NHS, amine reactive) functionalized cyclooctyne derivative for incorporation of the cyclooctyne moiety into amine containing compounds or biomolecules. Cyclooctynes are useful in strain-promoted copper-free click chemistry 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
