Used in research settings to measure levels of glutathione peroxidase enzyme activity in chicken biological samples such as serum, plasma, or tissue homogenates. This kit enables scientists to assess antioxidant status and oxidative stress in poultry, which is critical in studies related to animal health, nutrition, disease resistance, and environmental stress responses. It is commonly applied in veterinary research, poultry farming studies, and immunology to evaluate the impact of feed additives, toxins, infections, or vaccines on the chicken’s antioxidant defense system. The assay supports high-throughput analysis and provides quantitative data to compare enzyme activity across experimental groups.
