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. 物理性质： =============================================== 状态：淡黄色到黄色固体，或者半固体，取决于分子量。 溶解性：溶于DMSO,DMF等溶剂。 保持条件：-20℃长期保存，避光，干燥。 注意事项：取用一定要干燥，避免频繁的溶解和冻干。 反应性：DBCO于含有N3基团的反应。 技术指标： =============================================== 纯度（PEG）：90%以上 取代率（DBCO）：90%以上 取代率（FITC）：90%以上 分散系数（PDI）：小于等于1.05 分析：COA、GPC、NMR、MALDI-TOF
