Used in plant biology research to quantify arginine synthetase enzyme levels, helping assess nitrogen metabolism and stress responses in plants. Enables researchers to study polyamine biosynthesis pathways, particularly the role of spermidine synthase in growth, development, and environmental adaptation. Commonly applied in agricultural and physiological studies to evaluate plant health, nutrient utilization, and resilience under abiotic stresses such as drought, salinity, or extreme temperatures. Provides a reliable, sensitive method for measuring enzyme concentration in tissue extracts, supporting advancements in crop improvement and functional genomics.
