Used in plant biology research to quantify uridine diphosphate glucose pyrophosphorylase (UGPase) activity in plant tissues. This assay helps assess carbohydrate metabolism, particularly in pathways related to sucrose and starch biosynthesis. Researchers apply it in studies of plant development, stress responses, and energy allocation. The kit enables high-throughput analysis, making it valuable for screening enzyme activity under various physiological or environmental conditions. It is commonly used in agricultural science and plant physiology to understand metabolic regulation in crops and model plants.
