[Description]

Strain promoted alkyne azide cycloaddition (SPAAC) between strained cycloalkynes and azides is a useful bioconjugation method that eliminates the need for copper catalyst necessary for classical CuAAC click chemistry.



Cyanine5.5 DBCO is a cyclooctyne product containing Cyanine5.5 fluorescent dye. This fluorophore is used in bioimaging, biodistribution studies, and microscopy.


Cyanine5.5 DBCO can be used to conjugate the fluorophore with various azides.


[Uses]

Dibenzocyclooctyne-Cy5.5 (DBCO-Cy5.5) is a fluorescent dye. Dibenzocyclooctyne-Cy5.5 can be used to syntheses calcium-binding near-infrared fluorescent nanoprobe for bone tissue imaging[1].
