Used for quantitative detection of glutamine levels in plant tissue extracts, this research kit enables accurate measurement of glutamine concentration, which plays a key role in plant nitrogen metabolism and stress response studies. It is widely applied in agricultural research, plant physiology, and environmental stress experiments to assess plant health and metabolic activity. The assay supports high-throughput analysis, making it suitable for screening plant responses to fertilizers, drought, salinity, and pathogen attacks. Results are typically read using a microplate reader, providing reliable data for research in plant biochemistry and molecular biology.
