Used to measure ATP synthase activity in rat tissue samples, particularly in mitochondrial research. Commonly applied in studies related to cellular energy metabolism, oxidative phosphorylation, and mitochondrial dysfunction. Helps in evaluating the effects of drugs, toxins, or diseases such as neurodegenerative disorders, ischemia, and metabolic syndromes on ATP production. Suitable for use in neuroscience, cardiology, and toxicology research where mitochondrial performance is a key indicator. Provides a quantitative, high-throughput method for assessing enzyme function in experimental models.
