Used in biomedical research to measure levels of glutathione peroxidase enzyme in mouse samples, aiding in the study of oxidative stress and antioxidant defense mechanisms. Commonly applied in studies related to inflammation, aging, neurodegenerative diseases, and liver function in mouse models. Enables researchers to quantify enzyme activity in tissue homogenates, serum, or plasma with high sensitivity and specificity. Supports evaluation of therapeutic interventions targeting oxidative damage in preclinical research.
