Used to measure the activity of fatty acid beta-oxidation (FAβO) enzymes in mouse tissue samples, particularly in liver, muscle, or adipose tissue. Helps researchers study metabolic disorders such as fatty liver disease, insulin resistance, and mitochondrial dysfunction. Commonly applied in preclinical studies involving diet-induced obesity, diabetes models, and drug development targeting energy metabolism. Provides quantitative data to assess how genetic modifications or pharmaceutical treatments affect fat breakdown in mice.
