Used in biomedical research to measure thyroxine (T4) levels in porcine (pig) serum or plasma samples. This kit enables researchers to assess thyroid function in pigs, which is important in studies related to endocrinology, metabolic disorders, and reproductive health. It is commonly applied in veterinary research, pharmaceutical development, and animal physiology studies where accurate quantification of thyroid hormones is required. The ELISA format allows for high-throughput screening with high sensitivity and specificity, making it suitable for laboratory use in both academic and industrial settings.
