Used in biomedical research to measure levels of human mitochondrial cytochrome c oxidase (CCO) in tissue or cell samples. Helps assess mitochondrial function and electron transport chain activity, particularly in studies related to metabolic disorders, neurodegenerative diseases (like Alzheimer's and Parkinson's), aging, and mitochondrial myopathies. The kit enables quantitative analysis of CCO protein expression, supporting investigation into mitochondrial dysfunction and evaluation of potential therapeutic interventions targeting cellular energy metabolism. Commonly used in neuroscience, biochemistry, and clinical research laboratories.
