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. Cyanine 5.5 DBCO is a cyclooctyne product containing Cyanine 5.5 fluorescent dye. This fluorophore is used in bioimaging, biodistribution studies, and microscopy. Cyanine 5.5 DBCO can be used to conjugate the fluorophore with various azides.
