INTRODUCTION
Chitinase is a digestive enzyme which breaks down glycosidic bonds in chitin. Due to chitin being a component of the cell walls of fungi and exoskeletal elements of some animals (including worms and arthropods), chitinases are usually found in organisms that either need to remake their own chitin or to dissolve and digest the chitin of fungi or animals. Chitinivorous organisms include many bacteria genuses such as Aeromonas, Bacillus, Vibrio, among others, which may be pathogenic or detritivorous. Chitinase expression is mediated by the NPR1 gene and the salicylic acid pathway, both of which are involved in resisting fungal and insect attack. Human chitinases appear in gastric juices. They are likely to be digestive chitinases, for catabolic activity. Chitinase activity is identified systemically in humans, in the blood, and possibly cartilage. Chitinase has been related to allergies, asthma in particular has been linked to enhanced chitinase expression levels, also dust mites and mold spores which are both chitin covered.DESCRIPTION
Chitinase Clostridium Paraputrificum Recombinant fused with a His tag at N-terminus produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 582 amino acids and having a molecular mass of 64.2kDa.The Chitinase is purified by proprietary chromatographic techniques.
SOURCE
Escherichia Coli.PHYSICAL APPEARANCE
Sterile Filtered White lyophilized (freeze-dried) powder.FORMULATION
Chitinase lyophilized from a 0.2µm filtered concentrated solution in PBS.SOLUBILITY
It is recommended to reconstitute the lyophilized Chitinase in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.STABILITY
Lyophilized Chitinase although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Chitinase should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
PURITY
Greater than 95.0% as determined by SDS-PAGE.AMINO ACID SEQUENCE

文献和实验问:很多生物防治用的真菌可以产生几丁质酶和蛋白酶等代谢产物,现在实验想检测这两种酶的活性的大小,不知道用那种方法,请教各位!有没有简单的方法如平板法,测代谢产物法等,具体方法如何? 答:可以用透明圈法,具体做法就是提出几丁质粗酶液后在几丁质—PDA培养基上打孔培养一定时间然后观察透明圈的大小,测代谢产物应该是不行,因为几丁质酶分内外切酶,产物不一,测不出来的,你也可以用聚丙烯酰胺电泳检测。具体方法可以参考这篇文章Chitinase system of Bacillus circulans
Enzymatic Depolymerization of Chitins and Chitosans
of chitinases, but the comparative evaluation of the data obtained with other enzymes points to a different conclusion. In this chapter, the following depolymerization methods are presented and discussed: (1) chitinase on chitin, (2) chitosanase on chitin
