一、产品简介:
半纤维素酶主要检测木聚糖酶活力,可将木聚糖降解成低聚糖和木糖的一组酶的总称,广泛应用于酿造和饲料工业中。
半纤维素酶在酸性下将木聚糖降解成还原性寡糖和单糖,进一步与3,5-二硝基水杨酸发生显色反应,在540nm处有特征吸收峰,反应液颜色深浅与酶解产生的还原糖量成正比,通过测定反应液在540nm吸光值增加速率,即可计算该酶活力大小。
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)、低温离心机、恒温水浴锅、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!
