Used in biological research to measure levels of glutathione peroxidase enzyme in chicken samples, this ELISA kit enables detection and quantification of the enzyme's activity in serum, plasma, or tissue homogenates. It is particularly useful in studies related to oxidative stress, antioxidant defense mechanisms, and poultry health. Researchers apply it to evaluate the impact of diet, disease, or environmental factors on antioxidant capacity in chickens. The assay supports high-throughput analysis with good sensitivity and specificity, making it suitable for use in veterinary research, agricultural studies, and immunology labs.
