Used in biomedical research to detect and quantify thyroid peroxidase antibodies in rat serum samples. Helps in studying autoimmune thyroid diseases such as experimental autoimmune thyroiditis. Enables researchers to assess thyroid immune response in preclinical studies, monitor disease progression, and evaluate the effectiveness of therapeutic interventions targeting the thyroid system in rodent models. Widely applied in endocrinology and immunology research for high-throughput screening and mechanistic studies.
