WebJul 10, 2015 · Chitinase activity can also be detected in gels after electrophoresis by zymography staining by incorporating an assay substrate into the gel during casting. After electrophoresis, the chitinase activity band can be visualized by staining gel with 0.1 % Congo red or a fluorescent brightener [ 33 , 34 ]. WebThe addition of chitinase inhibitor(s) (1000 ppm) proportionally reduced the release of dye labelled GlcNAc from the substrate in the reaction mixture. Conclusions: The assay for chitinase activity measuring the release of dye-labelled GlcNAc was simple, rapid and sensitive. There was no need to measure GlcNAc using a separate colorimetric method. birdsall ny highway departments
