谷胱甘肽还原酶（GR）是广泛存在于真核和原核生物中的一种黄素蛋白氧化还原酶，是谷胱甘肽氧化还原循环的关键酶之一（通常昆虫中GR被硫氧还蛋白还原酶（TrxR）取代）。GR催化NADPH还原GSSG生成GSH，有助于维持体内GSH/GSSG比值，在氧化胁迫反应中对活性氧清除起关键作用，并参与抗坏血酸-谷胱甘肽循环途径。 本试剂盒的测定原理为：GR催化NADPH还原GSSG再生GSH，同时NADPH脱氢生成NADP⁺；NADPH在340 nm处具有特征吸收峰，而NADP⁺在该波长无吸收峰。通过测定340 nm处吸光度的下降速率，反映NADPH的脱氢速率，从而计算GR的酶活性。
Glutathione reductase (GR) is a flavoprotein oxidoreductase widely distributed in eukaryotes and prokaryotes, and is one of the key enzymes in the glutathione redox cycle (in insects, GR is typically replaced by thioredoxin reductase, TrxR). GR catalyzes the reduction of GSSG to GSH using NADPH as the electron donor, helping to maintain the intracellular GSH/GSSG ratio. It plays a critical role in scavenging reactive oxygen species during oxidative stress responses and is also involved in the ascorbate-glutathione cycle pathway. The assay principle of this kit is as follows: GR catalyzes the reduction of GSSG to regenerate GSH using NADPH, concomitantly oxidizing NADPH to NADP⁺. NADPH exhibits a characteristic absorbance peak at 340 nm, whereas NADP⁺ has no absorbance at this wavelength. By measuring the rate of decrease in absorbance at 340 nm, which reflects the rate of NADPH oxidation, the GR enzyme activity can be calculated.
