Used to measure NADPH-oxidase enzyme activity in plant samples, this ELISA kit helps researchers study reactive oxygen species (ROS) production in plant cells. It is widely applied in plant physiology and stress response studies, such as drought, salinity, pathogen attack, and heavy metal toxicity. By quantifying NADPH-oxidase activity, scientists can assess plant defense mechanisms, signal transduction pathways, and overall oxidative metabolism. The kit supports high-throughput analysis in agricultural research, environmental monitoring, and genetic studies aimed at improving crop resilience.
