Used to measure glutathione reductase (GSR) activity in mouse biological samples such as blood, tissue homogenates, and cell lysates. This ELISA kit enables researchers to quantify GSR levels in studies related to oxidative stress, antioxidant defense mechanisms, and redox status in mouse models. It is commonly applied in research on inflammation, neurodegenerative diseases, liver toxicity, and aging, where changes in glutathione metabolism play a critical role. The assay provides a sensitive and specific way to monitor enzyme activity, supporting both basic research and preclinical studies.
