一、产品简介：
当生物体遭受外界胁迫时，生物体内超氧阴离子等活性氧大量产生和积累，可作为生物体氧化胁迫的信号。因此在逆境条件下生物体内超氧阴离子自由基的产生，可间接反映组织细胞受损状况和抗性强弱。超氧阴离子（O2-）与羟胺反应产生NO2－，NO2－在对氨基苯磺酸和α-萘胺作用下，生成粉红色的偶氮染料，该染料在540nm处有最大光吸收，根据A540值可计算出样品中的O2-的含量。
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）、天平、水浴锅、离心机、研钵、可调式移液器、冰、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！
