Used for measuring thioredoxin reductase (TrxR) enzyme activity in rat tissue samples, this ELISA kit is essential in oxidative stress research. It allows researchers to quantify TrxR levels in studies related to inflammation, aging, cancer, and neurodegenerative diseases. Commonly applied in preclinical studies using rat models, it helps evaluate the impact of drugs, toxins, or antioxidants on cellular redox systems. The kit is widely used in pharmaceutical development and toxicology to assess liver injury, drug-induced oxidative damage, and immune responses. Its high sensitivity enables detection of subtle changes in enzyme activity, supporting accurate biomarker analysis in experimental biology.
