Used for detecting and quantifying aminopeptidase N (APN) enzyme activity in plant samples, this ELISA kit is essential in plant physiology and stress response studies. It enables researchers to monitor changes in APN levels under various environmental stresses such as drought, salinity, or pathogen attack. The kit supports investigations into nitrogen metabolism and protein turnover in plants, making it valuable in agricultural research and crop improvement programs. Its high sensitivity allows for precise measurement in small sample volumes, facilitating use in high-throughput screening of plant lines or treatments.
