一般描述

谷胱甘肽定量试剂盒用于检测氧化和还原性谷胱甘肽。 谷胱甘肽通常以还原性形式表示，称为谷胱甘肽；然而，GSH在氧化应激时转变为氧化态(GSSG)。GSH和GSSG的比值被认为是氧化应激的指标。 谷胱甘肽，又称γ-L-谷酰基-L-半胱氨酰甘氨酸，是一种参与抗氧化和药物代谢的三肽化合物。它是谷胱甘肽过氧化物酶、谷胱甘肽s转移酶和硫醇转移酶等酶的底物。

应用

谷胱甘肽定量试剂盒用于检测谷胱甘肽总量，作为氧化应激或疾病风险的指标。

特点和优势

试剂盒检测总谷胱甘肽和GSSG的范围分别为0.5 μmol/l至50 μmol/l和0.5 μmol/l至25 μmol/l。

组分

谷胱甘肽定量试剂盒包含：
  • 酶液(50µl X 1)
  • 缓冲液(60ml X 1)
  • 标准GSH (X 1)
  • 掩蔽剂 (20µl X 1)
  • 辅酶 (X 2)
  • 底物(DTNB) (X4)
  • 标准GSSG (X 1)

分析说明

谷胱甘肽定量试剂盒包含谷胱甘肽掩蔽剂。通过测定DTNB(’5,5-二硫代(2-硝基苯甲酸))与酶循环系统的比色反应获得的吸收(λmax = 412 nm)，从而实现了样品中的GSSG检测。 谷胱甘肽的总量可由谷胱甘肽的总量减去谷胱甘肽的总量来测定。

其他说明

未在韩国、新加坡、台湾和日本供应

Acute liver failure (ALF) impairs cerebral function and induces hepatic encephalopathy (HE) due to the accumulation of neurotoxic and neuroactive substances in the brain. Cerebral oxidative stress (OS), under control of the glutathione-based defense system, contributes to the HE pathogenesis.
