Used in plant biology research to quantify cytochrome P450 reductase (CPR) levels in plant tissue extracts. This ELISA kit enables scientists to study CPR's role in the metabolism of secondary metabolites, hormone biosynthesis, and detoxification processes. It is particularly useful in experiments involving plant responses to environmental stress, xenobiotics, or pathogen attack. The assay supports high-throughput analysis, making it suitable for screening plant varieties or genetic mutants with altered CPR expression. Results help in understanding electron transfer systems in plant cytochrome pathways and support metabolic engineering efforts in agriculture and biotechnology.
