一、试剂领路
Tris NTA 马来酰亚胺(Tris Nitrilotriacetic acid-Maleimide)是一种具有高亲和力、高特异性的双功能交联试剂,中枢用于含组氨酸标签(His-tag)卵白的靶向偶联、活性修饰及分子互相作用磋商,浩繁诓骗于生归天学、分子生物学、卵白质组学及药物研发等科研限制,是组氨酸标签卵白功能化修饰的中枢器具。
该试剂分子结构包含两个要道功能基团:一端为三齿氮川三乙酸(Tris NTA)基团,相较于普通NTA,其与镍离子(Ni²⁺)的螯合智商更强,可酿成更沉静的Tris NTA-Ni²⁺复合物,进而高效、特异性协调含组氨酸标签的卵白,协调亲和力显耀优于传统NTA试剂;另一端为马来酰亚胺(Mal)基团,可与含有巯基(-SH)的生物分子(如卵白质、多肽、抗体、荧光染料)发生特异性加成反映,酿成沉静的硫醚键,j9game收尾观念卵白的高效偶联与功能化修饰。
Tris NTA malemide is an excellent building block to develop probes for detecting polyHIS tag proteins. Tris NTA compounds probably have the highest affinity for polyhistidine-labeled proteins. They can be used for the purification and analysis of polyhistidine-tagged proteins. AAT Bioquest offers a large family of fluorescent tris-NTA compounds that provide an efficient method for site-specific and stable noncovalent fluorescence labeling of polyhistidine-tagged proteins. In contrast to the transient binding of conventional mono-NTA, the multivalent interaction of tris-NTA compounds form a much more stable complex with polyhistidine-tagged proteins. The high selectivity of tris-NTA compounds toward cumulated histidines enable the selective labeling of proteins in cell lysates and on the surface of live cells.
