Used to measure the activity of Carnitine Acylcarnitine Translocase (CACT) in mouse biological samples such as tissue lysates or mitochondrial preparations. This assay is commonly applied in research settings to study fatty acid metabolism, mitochondrial function, and metabolic disorders. It enables researchers to assess changes in CACT activity under various experimental conditions, including disease models like metabolic syndromes, diabetes, or cardiomyopathy. The kit supports quantitative analysis, allowing for precise comparison across samples and contributing to the understanding of mitochondrial transport mechanisms in health and disease.
