Used for detecting and quantifying plant cytochrome P450 reductase (CPR) activity in research settings, this ELISA kit enables scientists to study enzyme function in plant metabolism, detoxification processes, and responses to environmental stress. It is widely applied in plant physiology, agricultural research, and phytochemistry to evaluate how plants metabolize xenobiotics, synthesize secondary metabolites, and adapt to biotic and abiotic stresses. The assay provides a reliable, sensitive, and high-throughput method for monitoring changes in CPR levels under different experimental conditions, supporting advancements in crop improvement and environmental monitoring.
