Used in research settings to quantitatively measure levels of Glutathione Peroxidase 1 (GSH-PX1) in biological samples from rats. This ELISA kit enables scientists to assess antioxidant enzyme activity in tissues or serum, particularly in studies related to oxidative stress, inflammation, toxicology, and diseases such as diabetes, neurodegenerative disorders, and liver damage. The assay is valuable for evaluating the impact of drugs, environmental toxins, or dietary interventions on antioxidant defense mechanisms in rat models. High sensitivity and specificity make it suitable for detecting small changes in GSH-PX1 concentration, supporting reliable data collection in preclinical research.
