應(yīng)用簡介:
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.
物理性質(zhì):
狀態(tài):淡黃色到黃色固體,或者半固體,取決于分子量。
溶解性:溶于DMSO,DMF等溶劑。
保持條件:-20℃*保存,避光,干燥。
注意事項(xiàng):取用一定要干燥,避免頻繁的溶解和凍干。
反應(yīng)性:DBCO于含有N3基團(tuán)的反應(yīng)。
