MitoPQ is primarily used in research to study mitochondrial function and oxidative stress. It is designed to selectively target mitochondria, making it a valuable tool for investigating the role of reactive oxygen species (ROS) in cellular processes. Researchers use MitoPQ to model mitochondrial dysfunction, which is relevant in understanding diseases like Parkinson's, Alzheimer's, and other neurodegenerative disorders. Additionally, it helps in evaluating the effectiveness of antioxidants and other therapeutic agents aimed at mitigating mitochondrial damage. Its specificity for mitochondria allows for precise experimental conditions, providing insights into cellular metabolism and the impact of oxidative stress on aging and disease progression.
