Used in biomedical research to measure CPR (cytochrome P450 reductase) activity in mouse samples, particularly in liver tissue. Helps assess the functional status of the cytochrome P450 enzyme system, which plays a key role in drug metabolism and detoxification processes. The kit enables researchers to evaluate how genetic modifications, drug treatments, or disease states affect CPR activity in mouse models. Commonly applied in pharmacokinetic studies, toxicology research, and studies involving metabolic pathways. Provides a quantitative and sensitive method to monitor changes in enzyme activity, supporting drug development and mechanistic studies in preclinical models.
