2-Chloro-4-nitrophenyl b-D-cellobioside

Chromogenic substrate for cellulase activity. Suitable for kinetic characterisation of cellulases. Useful for biofuels research to measure cellulase activity for optimum ethanol production.

2-Chloro-4-nitrophenyl b-D-cellobioside (CNPG) is a chromogenic enzyme substrate that is commonly used to detect and measure the activity of beta-glucosidases. CNPG is cleaved by the enzyme into the chromogenic product, which can be detected spectrophotometrically. beta-glucosidases are important enzymes in the breakdown of cellulose, and CNPG is a widely used substrate for the detection and quantification of these enzymes in various research studies.
