Sulfo-dibenzocyclooctyne-biotin conjugate

This sulfonated azadibenzocyclooctyne-biotin derivative is a highly water soluble and versatile biotinylation reagent for labeling azide containing molecules or compounds. Cyclooctynes are useful in strain-promoted copper-free azide-alkyne cycloaddition reactions.This dibenzocyclooctyne will react with azide-functionalized compounds or biomolecules without the need for a Cu(I) catalyst to result in a stable triazole linkage. Subsequent labeled molecules can be purified using streptavidin or avidin affinity reagents.
