Used to measure thioredoxin reductase (TrxR) enzyme activity in mouse biological samples such as tissue lysates, blood, or cell extracts. This kit is commonly applied in research on oxidative stress, antioxidant defense mechanisms, and redox signaling pathways. It helps in studying diseases related to cellular redox imbalance, including cancer, neurodegenerative disorders, and inflammatory conditions. The assay enables high-throughput analysis in preclinical studies, allowing researchers to evaluate the impact of drugs, toxins, or genetic modifications on TrxR function in mouse models.
