一般描述
应用
该试剂盒提供了有效检测真菌和细菌生长培养基、巨噬细胞裂解物、以及纯化酶制剂中几丁质酶活性所需的所有试剂。此外,该试剂盒还提供三种不同的底物,可用于检测多种类型的几丁质酶活性:
- 4-硝基苯基-N,N′-二乙酰基β-D-几丁质-底物,适用于外切几丁质酶活性检测(几丁二糖酶活性)
- 4-硝基苯基-N-乙酰基-β-D-葡萄糖胺-底物,适用于外切几丁质酶活性检测(β-N-乙酰氨基葡萄糖苷酶活性)
生化/生理作用
几丁质酶也可基于它们对几丁质底物的酶促作用而进行分类。内切蛋白酶被定义为可催化几丁质链内部点的随机切割的酶。外切蛋白酶可催化从几丁质的非还原末端逐渐释放乙酰壳霉二糖或N-乙酰葡糖胺,并分别称为壳二糖苷酶和β-N-乙酰葡糖胺酶。
几丁质酶在不同的生物体中发挥不同的功能。在细菌中,它们主要参与营养过程。在酵母和各种真菌中,这些酶参与形态发生。在动物和植物中,几丁质酶主要在防御病原体攻击中发挥作用。

What has Product CS0980, Chitinase Assay Kit, been tested on?
This kit has been tested on Trichoderma viride, Streptomyces griseus and human macrophages.
What is the recommended substrate concentration for Product CS0980, Chitinase Assay Kit?
A 1mg/mL substrate solution is recommended. If required, the 4-Nitrophenyl-beta-D-N,N',N''-triacetylchitotriose and the 4-Nitrophenyl N,N'-diacetyl-beta-D-chitobioside can be used at lower concentrations in the reaction (0.5 or 0.2mg/mL respectively).
How do you make the substrate in Product CS0980, Chitinase Assay Kit, go into solution?
The substrates do not dissolve easily in the buffer. It may take ~1 hour of shaking to completely dissolve the substrates. Use of a larger container (15 mL) may aid dissolution.
What is the stability of the Product CS0980, Chitinase Assay Kit, substrate solution (s)?
The substrate solution(s) should be stored on ice during the experiment. For storage up to one month, freeze at -20°C or below.
How many reactions will each substrate in Product CS0980, Chitinase Assay Kit, provide?
If used at a concentration of 1mg/mL: * 4-Nitrophenyl N-acetyl-b-D-glucosaminide (Product No. N9376) -100 reactions; * 4-Nitrophenyl N,N’-diacetyl-b-D-chitobioside (Product No. N6133) -50 reactions; * 4-Nitrophenyl-b-D-N,N',N''-triacetylchitotriose (Product No. N8638) -10 reactions.
