Used to measure fatty acid oxidation (FAO) activity in human biological samples, this ELISA kit enables researchers to assess mitochondrial function and energy metabolism. It is commonly applied in studies related to metabolic disorders, such as fatty acid oxidation defects, insulin resistance, and type 2 diabetes. The kit supports investigation into the effects of drugs, nutrients, or genetic modifications on FAO pathways. It is also utilized in clinical research to evaluate metabolic health in patient samples and to monitor responses to therapeutic interventions.
