Used in biochemical and medical research to measure glutathione peroxidase activity in duck samples, this ELISA kit enables detection of oxidative stress levels in avian tissues. It is commonly applied in veterinary research, poultry health studies, and environmental toxicity assessments where monitoring antioxidant defenses is critical. The kit supports quantitative analysis of enzyme expression in response to diseases, nutritional supplements, or exposure to pollutants, aiding in the evaluation of cellular protection mechanisms in ducks. Its high sensitivity and specificity make it suitable for use in laboratories focusing on avian immunology, oxidative damage, and disease resistance.
