Used for the quantitative measurement of glutamate dehydrogenase (GDH) enzyme activity in plant samples, this ELISA kit enables researchers to assess nitrogen metabolism and stress responses in plants. It is widely applied in plant physiology and agricultural research to study how plants respond to environmental stresses such as drought, salinity, and nutrient deficiency. The kit supports high-throughput analysis, making it useful in breeding programs and genetic studies aimed at improving crop resilience and nitrogen use efficiency.
