谷胱甘肽还原酶（GR，EC 1.6.4.2）广泛存在于动植物中，属于黄素蛋白氧化还原酶，催化氧化型谷胱甘肽（GSSG）还原为还原型谷胱甘肽（GSH）。GSH/GSSG比值越高，清除氧化胁迫产生的活性氧能力越强，因此GR活性是衡量氧化应激能力的重要指标。本试剂盒基于Ellman方法，利用DTNB与GR催化GSSG还原生成的GSH反应，生成黄色产物TNB，该产物在412 nm处有最大吸收峰。TNB的生成量与GR活性呈线性正相关，通过测定412 nm处吸光度的变化，即可计算GR的活性水平。该方法在可见光下检测，相较于传统方法，具有灵敏度高、产物稳定、操作简便等优势。
Glutathione reductase (GR, EC 1.6.4.2) is a flavoprotein oxidoreductase widely distributed in animals and plants. It catalyzes the reduction of oxidized glutathione (GSSG) to reduced glutathione (GSH). A higher GSH/GSSG ratio indicates a greater capacity to scavenge reactive oxygen species generated from oxidative stress; therefore, GR activity is an important indicator of oxidative stress resistance. This kit is based on the Ellman method, in which DTNB reacts with the GSH generated from the GR-catalyzed reduction of GSSG to form a yellow product, TNB, which exhibits a maximum absorbance peak at 412 nm. The amount of TNB produced is linearly proportional to GR activity. By measuring the change in absorbance at 412 nm, the GR activity level can be calculated. This visible-light detection method offers advantages over conventional methods, including high sensitivity, stable product formation, and simple operation.
