以半胱胺修饰的金纳米颗粒为载体,建立了一种操作简单的比色法测定谷胱甘肽S转移酶活性。该方法是基于GST能催化1-氯-2,4-二硝基苯(CDNB)和谷胱甘肽(GSH)生成偶联物(CDNB-SG)。GSH可以诱导AuNPs的聚集,而结合物不能诱导AuNPs的聚集。因此,GST活性可以很容易地用肉眼或简单的比色读数来测定。该方法简便、简便的比色反应使其成为一种有吸引力的药物筛选应用方法。
An operationally simple colorimetric method for measuring glutathione S-transferase (GST) activity was developed using cysteamine-capped gold nanoparticles (AuNPs) in this work. This method was based that GST can catalyze the reaction of 1-chloro-2,4-dinitrobenzene (CDNB) and glutathione (GSH) to produce a conjugate (CDNB-SG). GSH could induce the aggregation of AuNPs, whereas the conjugate could not induce the aggregation of AuNPs. Thus, GST activity can be facilely assayed with the naked eye or a simple colorimetric reader. The convenient and simple colorimetric response of the assay makes them an attractive approach for drug-screening application.
