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:
酶标仪(波长设置:540nm)、96孔酶标板、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!
