Used in biomedical research to quantify levels of thioredoxin reductase 1 in human samples, this ELISA kit supports studies on oxidative stress, cellular redox regulation, and antioxidant defense mechanisms. It is widely applied in investigating diseases linked to redox imbalance, including cancer, neurodegenerative disorders, and inflammatory conditions. Researchers use it to evaluate the impact of drugs, toxins, or therapeutic interventions on TXNRD1 expression in cell lysates, serum, or plasma. Its high sensitivity and specificity make it suitable for clinical and experimental settings where accurate measurement of enzyme levels is critical for understanding disease mechanisms and developing targeted treatments.
