应用简介:
DBCO (dibenzocycolctyne) PEG ACA (DBCO-PEG-ACA) derivatives can go Click Chemistry reaction without a need of any metal catalysts. The strain-promoted 1,3-dipolar cycloaddition of cyclooctynes and azides, also termed as the Cu-free click reaction, is a bioorthogonal reaction that enables the conjugation of two molecules in aqueous solution. DBCO PEG derivatives possess fast kinetics and stability in aqueous buffer. DBCO reagents can be used to label azide-modified biomolecules spontaneous without the need for toxic Cu catalysts. PEGylation can increase solubility and stability and reduce immunogenicity of peptides and proteins. It can also suppress the non-specific binding of charged molecules to the modified surfaces.(DBCO(二苄环炔)PEG-ACA(DBCO-PEG-ACA)衍生物无需任何金属催化剂即可进行点击化学反应。该菌株促进了环辛烷和叠氮化物的1,3-偶极环加成,也称为无铜点击反应,是一种生物正交反应,使两个分子在水溶液中结合。DBCO-PEG衍生物在水缓冲液中具有快速的动力学和稳定性。DBCO试剂可以自动标记叠氮化物修饰的生物分子,而不需要使用有毒的铜催化剂。聚乙二醇化可以提高多肽和蛋白质的溶解性和稳定性,它还可以抑制带电分子与修饰表面的非特定结合。)
Copper-free Click Reaction Procedures:
Prepare the azide-containing reagents in reaction buffer.
Add DBCO reagents to azide containing reagents. Add 1 mol equivalent of limiting reagent to 1.5~3.0 mol equivalents of abundance reagent.
Incubate the reaction at room temperature for 2~4 hours or 2~12 hours at 4℃.
Purify conjugates either by dialysis or size-exclusion chromatograph.
