一、产品简介：
谷胱甘肽过氧化物酶（GPx，EC 1.11.1.9）代表一种具有过氧化物酶活性的酶家族，在保护生物免受氧 化损伤中起重要作用。以往以过氧化氢为底物进行检测，则会受到分解过氧化氢的过氧化氢酶(Catalase)的干扰，本试剂盒提供的有机过氧化物试剂(Cum-OOH)不会被过氧化氢酶分解，因而可以特异地检测出谷胱甘肽过氧化物酶的活力。 因此本试剂盒可以定量检测总谷胱甘肽过氧化物酶。GSH 和 DTNB 反应产生黄色物质，后者在 412nm 下有最大吸收峰，而 GSH-Px 催化有机过氧化物试剂(Cum-OOH)氧化 GSH，使 GSH 量减少，GSH 量减少越多，反应混合液黄色越浅，则 GSH-Px 活性越大；反之，黄色越深，GSH-Px 活性越低。
二、所需的仪器和用品：
可见分光光度计、1mL 玻璃比色皿（光径 1cm）、低温离心机、移液器、研钵。

1、问：官网上试剂盒规格标注的“24样”、“48样”、“96样”是什么意思呢？
答：“24样”、“48样”、“96样”是试剂盒规格，我们定义了试剂盒可以测多少样，对于试剂盒需要的试剂量都给足的。
“24样”、“48样”、“96样”规格的试剂盒，可以检测24个样、48个样、96个样；即分别得到24个、48个、96个数据。
2、问：官网上试剂盒检测方法中"可见分光法/紫外分光法"与“微板法”是什么区别？
答：分光法：指使用紫外可见分光光度计检测，若无紫外可见光分光度计，订购时务必咨询公司技术。公司分光法试剂盒采用的比色皿规格是：光径：1cm,容积：1mL, 狭缝宽3mm;
微板法：指使用全波段连续酶标仪检测；若无全波段酶标仪，订购指标时务必咨询公司技术， 本公司微板法试剂盒内送96孔普通酶标板，客户无需另外购买耗材。
3、问：分光法试剂盒与微板法试剂盒是否能通用？
答：公司针对用户实验室具备的实验仪器条件，做了两个体系的试剂盒。两种体系试剂盒检测指标的原理一样，结果可以通用，但是不同体系的试剂盒不可以相互混匀！
