Used in biomedical research to measure levels of Carnitine Palmitoyl Transferase-II (CPT-II) in human tissue or serum samples. Helps investigate mitochondrial fatty acid oxidation disorders, particularly those linked to genetic deficiencies in CPT-II enzyme activity. Supports studies on metabolic diseases, muscle dysfunction, and neurodegenerative conditions where mitochondrial energy metabolism is impaired. Enables researchers to assess enzyme expression changes in response to drugs, diet, or disease states, contributing to diagnostic development and therapeutic monitoring in metabolic research.
