Used in biomedical research to quantitatively measure levels of mitochondrial respiratory chain complex II in rat tissue samples, particularly in studies related to mitochondrial function and dysfunction. Commonly applied in research on neurodegenerative diseases, ischemia-reperfusion injury, and metabolic disorders where mitochondrial integrity plays a critical role. Enables researchers to assess the impact of drugs, toxins, or genetic modifications on mitochondrial complex II expression and activity in rat models. The ELISA format allows for high-throughput analysis with high specificity and sensitivity, making it valuable in preclinical studies and mechanistic investigations.
