一、产品简介：
土壤过氧化氢酶主要分解土壤中的过氧化氢，降低土壤中过度累积的过氧化氢对植 物根系的危害。本试剂盒提供一种简单，灵敏，快速的测定方法，即 CAT 催化过氧化 氢产生水与氧气，剩余的过氧化氢与一种高灵敏显色探针反应生成有色物质，其在 510nm 左右有最大吸收峰。通过过氧化氢的减少量来计算土壤中 CAT 酶的活力。 本试剂盒突出特点是从紫外波长（240nm：过氧化氢的检测波长）转换到可见波长 （510nm）检测，无需使用石英比色皿或 UV 板。而且由于过氧化氢极其不稳定，直接 检测造成读值不稳定，且蛋白质等组分在此紫外波长下也有光吸收，影响结果精确性。
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）、台式离心机、水浴锅、可调式移液器

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！
