Dojindo,Biotin-SS-Sulfo-OSu/100/B572,Biotin-SS-Sulfo-Osu有N-羟基琥珀酰亚胺活性酯基团生物素分子

Biotin-SS-Sulfo-Osu是一种含有N-羟基琥珀酰亚胺活性酯基团的生物素分子,可用于将生物素引入抗体、酶等蛋白质的氨基基团。 与仅具有烷基链接头的生物素化试剂、Biotin-AC5Sulfo-OSu 或 Biotin Sulfo-OSu 不同,接头位点的切割是可能的,但是引入接头位点的二硫基团很容易被还原剂还原。 在涂有抗生物素蛋白或链霉抗生物素蛋白的柱上使用 Biotin-SS-Sulfo-OSu 标记分子后,可以通过还原操作切割接头位点来回收分子。
