The Polygalacturonase (PG) Activity Assay Kit is widely used in various industries and research fields to measure the activity of the enzyme polygalacturonase. In the food industry, it is employed to assess the quality and ripeness of fruits and vegetables, as PG plays a key role in pectin degradation, affecting texture and shelf life. In agricultural research, the kit helps in studying plant-pathogen interactions, as PG is often secreted by pathogens to break down plant cell walls. Additionally, it is utilized in the production of fruit juices and wine to optimize enzymatic processes that improve juice yield and clarity. In biotechnology, the kit aids in enzyme characterization and screening for industrial applications, such as biofuel production and waste management.
