一般說明
细胞谷胱甘肽过氧化物酶活性检测试剂盒用于对组织提取物中的谷胱甘肽过氧化物酶进行定量检测。本试剂盒基于谷胱甘肽（GSH）氧化后可生成氧化型谷胱甘肽（GSSG）。利用谷胱甘肽过氧化物酶（GPx）将GSH氧化成GSSG，生成的GSSG在谷胱甘肽还原酶（GR）的催化下再次生成GSH以及NADP+NAPDH氧化为NADP+的过程伴随340 nm处吸收光的减少。此处吸收值减少与样本中谷胱甘肽过氧化酶活性呈正相关。
適合性
适用于测定组织提取物中的谷胱甘肽过氧化物酶
原則
谷胱甘肽过氧化物酶细胞活性测定试剂盒用于测定组织提取物中的谷胱甘肽过氧化物酶。该测定基于将谷胱甘肽（GSH）氧化为氧化型谷胱甘肽（GSSG）。这一反应由GPx催化，并用谷胱甘肽还原酶和NADPH将GSSG再循环回GSH。由于该酶是偶联反应的限速因子，因此在NADPH氧化成NADP的过程中，可通过测定340nm处NADPH吸光度的降低，表明谷胱甘肽过氧化物酶的活性。
其他說明
本试剂盒通过了兔网织红细胞裂解液和谷胱甘肽过氧化物酶的测试。

Oxidative stress is mediated, in part, by reactive oxygen species produced by multiple cellular processes and controlled by cellular antioxidant mechanisms such as enzymatic scavengers or antioxidant modulators. Free radicals, such as reactive oxygen species, cause cellular damage via cellular.
