Biomolecule labeling continues to be a cornerstone feature of many in vitro and in vivo biological experiments. Click Chemistry has recently emerged as a convenient, versatile, and reliable method for labeling a wide variety of molecules for applications ranging from biomarker isolation to assay development.
LI-COR offers a portfolio of click chemistry reagents for copper-catalyzed and copper-free methods. These products offer researchers flexibility to choose the correct reagent for a diverse array of applications. LI-COR click chemistry reagents include IRDye® 800CW, IRDye 680RD, and IRDye 650 infrared fluorescent dyes labeled with DBCO, azide, or alkyne groups.
Click chemistry utilizes pairs of reagents that exclusively react with each other and are effectively inert to naturally-occurring functional groups such as amines. Unlike affinity interactions such as streptavidin-biotin, click chemistry forges covalent bonds between the reacting partners to deliver stable bioconjugates.
Click chemistry reactions can be categorized into two separate groups, copper-catalyzed or copper-free. Copper-catalyzed click chemistry is used for initiating reactions between azides and alkynes. These reactions are also known as Copper-Catalyzed Azide-Alkyne Cycloaddition (CuAAC). Although they initiate and accelerate click reactions, copper catalysts are cytotoxic and inappropriate for use in living systems.
