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.
Application:	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
Packaging:	1, 5, 50 mg in clear glass bottle
