Used for the quantitative measurement of fatty acid beta-oxidation (FAβO) activity in human biological samples such as plasma, serum, or tissue extracts. This ELISA kit enables researchers to assess mitochondrial function and metabolic health, particularly in studies related to metabolic disorders like diabetes, obesity, and fatty liver disease. It is also applied in clinical research to evaluate the impact of genetic mutations affecting fatty acid metabolism and to monitor responses to therapeutic interventions targeting energy metabolism pathways. The assay is widely used in diagnostic laboratories and biomedical research for its sensitivity and specificity in detecting changes in FAβO enzyme activity.
