一、产品简介：
抗坏血酸过氧化物酶（APX；EC 1.11.1.11)也称维生素 C 过氧化物酶，是植物细胞中防御外界氧化胁迫和植物本身活性氧代谢的重要抗氧化酶类，在降低 H2O2对植物细胞产生氧化损伤方面起关键作用。抗坏血酸过氧化物酶（APX）首先与 H2O2 形成中间复合物，中间复合物接着氧化 AsA，因此 APX 与 AsA 具有一定的负相关性，通过测定 AsA 氧化速率，来计算 APX 酶活性。
二、所需仪器和用品：
紫外分光光度计、1mL 石英比色皿（光径 1cm）、低温离心机、移液枪、研钵、冰和蒸馏水。

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！
