应用简介:
=========================================
DBCO (Dibenzocyclooctyne) is a cycloalkyne that can reacts with azides via strain-promoted 1,3-dipolar cycloaddition in aqueous solution, a bioorthogonal reaction also termed Cu-free click reaction. This reaction has excellent selectivity and biocompatibility, such that the complimentary reagents can form covalent bonds with richly functionalized biological systems. The Cu-free click reaction has been a powerful tool in catalyst-free bioconjugation. DBCO reagents posses fast kinetcs and stability in aqueous buffer and they can be used to label azide-modified biomolecules with high specificity and reactivity.
Copper-free Click Reaction Procedures:
Prepare the azide-containing sample in reaction buffer. Add DBCO conjugate to azide containing sample. Recommendation: Add 1 mole equivalent of limiting reagent to 1.5-3.0 mole equivalents of highest abundance reagent. Incubate the reaction at room temperature for 2-4 hours or 2-12 hours at 4 degree celcius. The reaction is now ready for purification.
