一、产品简介：
土壤蔗糖酶又叫土壤蔗糖转化酶，因其在酸性介质中活性最大，因此土壤中常测的蔗糖酶亦是酸性转化酶。其对增加土壤中易溶性营养物质起着重要的作用，与土壤中的有机质、氮、磷含量、微生物活动和土壤呼吸强度有关，一般情况下，土壤肥力越高，蔗糖酶活性越强，因此该酶也是评价土壤熟化程度和肥力水平的一个指标。本试剂盒采用 DNS 比色法，即土壤蔗糖酶催化蔗糖降解产生还原糖，进一步与 3,5－二硝基水杨酸反应，生成有色氨基化合物，在 540nm 有特征光吸收，在一定范围内 540nm光吸收增加速率与土壤蔗糖酶活性成正比。
二、所需的仪器和用品：
可见分光光度计（波长设置：540nm）、1mL 玻璃比色皿（光径 1cm）、台式离心机、水浴锅/恒温培养箱、 可调式移液器、甲苯

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！
