m-dPEG®12-DBCO,产品编号QBD-10596,是一种甲氧基封端的离散聚乙二醇(dPEG®)点击化学试剂,设计用于通过应力促进叠氮化物-炔环加成(SPAAC)进行表面化学改性。从末端甲基到二苄基环辛炔(DBCO)基团上的反应性位点,dPEG®间隔基为39个原子长。

m-dPEG®12-DBCO, product number QBD-10596, is a methoxy-terminated, discrete polyethylene glycol (dPEG®) click chemistry reagent designed for chemical modification of surfaces through strain-promoted azide-alkyne cycloaddition (SPAAC). From the terminal methyl group to the reactive site on the dibenzylcyclooctyne (DBCO) group, the dPEG® spacer is 39 atoms long.DBCO was designed for bio-orthogonal click chemistry applications using SPAAC, also known as copper-free click chemistry, which was developed by Carolyn Bertozzi and colleagues to avoid the potential toxicity of Cu(I) that is used in Copper(I)-Promoted Azide Alkyne Cycloaddition (CuAAC) discovered by K. Barry Sharpless and colleagues. The dPEG® spacer differs from traditional PEG spacers and linkers in that it consists of a single molecular weight and chain length of PEG (i.e., it is monodispersed), which simplifies analysis of conjugates made with this compound.Potential uses for this product include modifying alkyne-functionalized surfaces and peptides and proteins containing alkyne-functionalized amino acid side chains.

文献和实验为His-tag 与 Strep-tag® 系统的耐受缓冲液对比 如果分离纯化膜蛋白或包涵体时,则纯化过程需要涉及到变性条件。 Strep-tag®系统最多允许的尿素浓度为6M,盐酸胍为1M,而His-tag 则为8M和6M。如若需要增加蛋白的溶解度,使用去垢剂,则两种系统均可兼容Triton-X100,Tween 20和Nonidet P40。 但不是所有的蛋白过表达后都在包涵体内,且膜蛋白仅占细胞表达蛋白的20%-30%。 因此,如果纯化过程需要考虑特殊的纯化条件,两种系统是都可以选择的。但如果比较
