Used in biochemical and medical research to measure levels of thioredoxin (Trx) in rat samples, this ELISA kit enables the quantification of redox protein activity associated with cellular antioxidant defense. It is widely applied in studies involving oxidative stress, inflammation, neurodegenerative diseases, and cancer in rodent models. Researchers use it to assess the impact of drugs, toxins, or genetic modifications on the redox state within tissues or biological fluids. The assay provides high sensitivity and specificity, making it suitable for monitoring changes in Trx expression under experimental conditions.
