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

The past three decades have witnessed notable advances in establishing photosensitizer-antibody photo-immunoconjugates for photo-immunotherapy and imaging of tumors. Photo-immunotherapy minimizes damage to surrounding healthy tissue when using a cancer-selective photo-immunoconjugate, but requires a threshold intracellular photosensitizer concentration to be effective.

Protein detection and quantification play critical roles in both basic research and clinical practice. Current detection platforms range from the widely used ELISA to more sophisticated, and more expensive, approaches such as digital ELISA. Despite advances, there remains a need
