發布時間:2018-8-1Dde Biotin Picolyl Azide
Dde Biotin Picolyl Azide is a unique amine reactive, cleavable biotin probe that allows for release of the captured biomolecules from streptavidin under mild conditions. This reagent contains a biotin moiety linked to picolyl azide moety through a spacer arm containing a hydrazine cleavable Dde moiety. Captured biomolecules can be efficiently released, typically >90% with 2% hydrazine in aqueous media.
Dde Biotin Picolyl Azide incorporates a copper-chelating motif that dramatically accelerates the Cu(I)-catalyzed azide−alkyne cycloaddition (CuAAC) reaction under conditions relevant to biomolecular labeling. Discovery of azides with an internal Cu(I)-chelating motif greatly enhances the utility of CuAAC reaction for monitoring the dynamic glycan biosynthesis in living organisms, the sensitive detection of metabolically labeled proteins DNAs and RNAs, and for many other application where rate acceleration and reduced cell toxicity are highly desirable.
Dde生物素Picolyl疊氮化物是一種*的胺反應性、可裂解性生物素探針,可以在溫和的條件下釋放從streptavidin捕獲的生物分子。該試劑含有生物素部分,通過含有可裂解的肼部分的隔離臂與異丙醇疊氮化物連接。捕獲的生物分子可以被有效釋放,通常>90%和2%肼在水介質中。
Dde生物素甲基吡啶疊氮化物結合了copper-chelating圖案,極大地加快了疊氮化銅(I)催化炔烴−環加成作用(CuAAC)反應條件下相關生物分子標記。具有內部Cu(I)螯合基序的疊氮化物的發現,極大地提高了CuAAC反應在生物體內監測動態糖生物合成、對代謝標記蛋白DNAs和RNAs的靈敏檢測,以及在許多其他需要加速和降低細胞毒性的應用上的效用。
