一般描述
生物素聚环氧乙烷（PEO）碘乙酰胺是巯基（硫醇）特异性生物素化试剂。
应用
生物素聚氧化乙烯碘乙酰胺已被用作巯基反应试剂，以证明人乳头瘤病毒 16 的衣壳蛋白 L1 中存在游离巯基。已用于 ELISA（酶联免疫吸附试验）竞争和牵出试验的蛋白生物素化。
- 包含一个 12 原子亲水间隔区。
- pH 7.5-8.5 通常与巯基偶联
- 在许多蛋白质组学类型应用（如肽图和质谱）中，半胱氨酸标记尤其有用。
生化/生理作用
生物素聚环氧乙烷（PEO）碘乙酰胺基团在pH 7.5-8.5下与还原的硫醇发生特异性反应。含有巯基的肽和小分子也可用该试剂标记。生物素PEO碘乙酰胺能够标记半胱氨酸残基并与蛋白质中的巯基偶联，从而使其可用于蛋白质组学、肽图分析、磷酸肽分析和质谱分析。

There are several techniques for biotinylating antibodies, from the most basic (using NHS-ester biotin to label primary amines) to more complex experiments (modifying sulfhydryls and carbohydrates). Biotinylation of free sulfhydryls, described here, can be effectively mediated using haloacetyl biotin derivatives.
