應(yīng)用簡(jiǎn)介:
Maleimide PEG DBCO (dibenzocycolctyne) is DBCO PEG derivatives that 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 aueous solution. DBCO PEG derivatives possess fast kinetics and stability in aueous buffer. DBCO reagents can be used to label azide-modified biomolecules spontaneous without the need for toxic Cu catalysts. Meanwhile, maleimide group can react with sulfhydryl (Thoil) groups at pH 6.5-7.5 easily. 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.
Copper-free Click Reaction Procedures:
Prepare the azide-containing reagents in reaction buffer.
Add DBCO reagents to azide containing reagents. Add 1 mol euivalent of limiting reagent to 1.5~3.0 mol euivalents 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.
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℃長(zhǎng)期保存,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)。MAL可以和SH。
