Used in biochemical and medical research to quantify levels of mitochondrial respiratory chain complex III in rat tissue samples. Helps assess mitochondrial function in studies related to cellular energy metabolism, oxidative stress, and diseases involving mitochondrial dysfunction such as neurodegenerative disorders, cardiovascular diseases, and aging. The kit enables sensitive and specific detection of complex III proteins, supporting research in pharmacology, toxicology, and molecular biology where mitochondrial health is a key indicator.
