一般描述

溴乙烷也被称为硫醇探针，是一种通过光解反应激活的荧光试剂。溴乙烷在溶液中与小硫醇基团（比如 GSH）和有反应活性的蛋白硫醇基团（如 血红蛋白）反应。 溴乙烷与硫醇的反应是二级反应，和pH相关。并且，通过与硫醇反应，激活了用于检测的水溶性荧光物质。

应用

溴乙烷被用于通过HPLC测定硫醇。 它适用于作为荧光测定2,3-二巯基丙烷-1-磺酸和其他二硫醇的柱前衍生试剂。 溴乙烷被用做研究牛心脏线粒体中对寡霉素敏感的ATP酶的荧光标记。

特点和优势

用溴乙烷分析低分子量硫醇的好处在于： 高选择性。
  • 反应快速。
  • 易于通过反相HPLC分离衍生物。
  • 能穿透细胞。

包装

无底玻璃瓶。内含物在插入的融合锥体内。

The increasing therapeutic use of dithiol metal binding agents, such as 2,3-dimercaptopropane-1-sulfonic acid (DMPS), has stimulated the need for a sensitive and selective method for their determination in biological fluids. A method has now been developed in which DMPS was
