Used in biomedical research to quantify levels of cytochrome P450 reductase (CPR) in mouse tissue samples, particularly in liver and other metabolically active tissues. Enables assessment of CPR expression under various experimental conditions such as drug treatment, toxic exposure, or genetic modification. Supports studies on drug metabolism, xenobiotic detoxification, and oxidative stress by providing a reliable measure of CPR, a key enzyme involved in electron transfer to cytochrome P450 enzymes. Widely applied in preclinical research to evaluate metabolic enzyme regulation and liver function in mouse models.
