Used in research settings to quantify cellulase enzyme activity, particularly the Cx component, in plant and microbial samples. Enables accurate measurement of enzyme levels in studies related to biomass degradation, biofuel production, and plant cell wall metabolism. Commonly applied in agricultural research, industrial enzyme development, and environmental microbiology to assess cellulolytic efficiency and optimize enzyme formulations. Suitable for high-throughput screening and kinetic studies due to its specificity and sensitivity in detecting active cellulase forms.
