Used in biochemical and biomedical research to quantify levels of mitochondrial respiratory chain complex III, specifically derived from pig tissue. Enables assessment of mitochondrial function in studies related to cellular energy metabolism, oxidative stress, and diseases affecting the respiratory chain. Commonly applied in veterinary research, toxicology, and preclinical studies involving porcine models. Supports investigation into mitochondrial dysfunction in conditions such as neurodegenerative disorders, metabolic diseases, and aging. The kit allows for high-sensitivity detection in tissue homogenates, cell lysates, and isolated mitochondria, facilitating accurate measurement of complex III protein concentration in experimental samples.
