Copper free click chemistry linkers have been widely used for in vivo bioconjugation applications. Conventional “Click Chemistry” requires the presence of cytotoxic of Cu(I) catalyst, which limits its applications in biological systems. The Copper-free Click Chemistry is based on the reaction of a cyclooctyne (DBCO and BCN) moiety with an azide-labeled reaction partner, known as strain-promoted alkyne azide cycloaddition (SPAAC).
