Polygalacturonase (PG) Activity Assay Kit is widely used in the food industry to assess enzyme activity in fruit processing. It helps determine the optimal conditions for juice extraction and clarification by measuring the breakdown of pectin. In the agricultural sector, this kit is employed to study fruit ripening and softening, aiding in the development of post-harvest treatments to extend shelf life. Additionally, it is utilized in research to understand plant-pathogen interactions, as PG enzymes play a role in microbial infection processes. The kit is also valuable in biotechnology for screening and optimizing microbial strains used in industrial enzyme production.
