Used to measure asparagine synthetase (ASNS) enzyme activity in plant samples, this ELISA kit helps researchers study nitrogen metabolism and stress responses in plants. It is commonly applied in agricultural research to evaluate how crops respond to environmental stresses like drought, salinity, or nutrient deficiency. By quantifying ASNS levels, scientists can identify plant varieties with improved nitrogen use efficiency, supporting the development of more resilient and sustainable crop systems. The kit is also useful in physiological studies aiming to understand amino acid biosynthesis and metabolic adaptation in plants.
