General description
Application
The kit provides all the reagents required for efficient detection of chitinase activity in fungal and bacterial growth media, macrophage lysates, and purified enzyme preparations. In addition, the kit provides three different substrates for the detection of the various types of the chitinolytic activity:
- 4-Nitrophenyl N,N′-diacetyl-β-D-chitobioside - substrate suitable for exochitinase activity detection (chitobiosidase activity)
- 4-Nitrophenyl N-acetyl-β-D-glucosaminide - substrate suitable for exochitinase activity detection (β-N-acetylglucosaminidase activity)
Biochem/physiol Actions
The chitinolytic enzymes are also categorized based on their enzymatic action on chitin substrates. Endochitinases are defined as the enzymes catalyzing the random cleavage at internal points in the chitin chain. Exochitinases catalyze the progressive release of acetylchitobiose or N-acetylglucosamine from the non-reducing end of chitin, and are referred to as chitobiosidase and β-N-acetylglucosaminidase, respectively.
Chitinases perform different functions in different organisms. In bacteria, they are mainly involved in nutritional processes. In yeast and various fungi, these enzymes participate in morphogenesis. In animals and plants, chitinases primarily play a role in the defense of the organism against pathogen attack.

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.
