BCN-PEG4-Cyanine3 (exo)
BCN-PEG4-Cyanine3 contains functional group bicyclononyne linked to a fluorophore Cyanine3. Bicyclo[6.1.0]nonyne (BCN) is a cyclooctyne with a significantly improved reactivity profile of strain-promoted azide-alkyne cycloaddition.
Conjugation of cyclooctyne constructs is used for labeling monoclonal antibodies containing an azido-functionalized amino acid with high conversion via copper-free click conjugation [1].
