Thyroglobulin from bovine thyroid gland is primarily used in medical and biochemical research to study thyroid function and related disorders. It serves as a key antigen in immunoassays for detecting autoimmune thyroid diseases, such as Hashimoto's thyroiditis and Graves' disease. Researchers also utilize it to produce antibodies for diagnostic purposes. In addition, thyroglobulin is employed in the development of thyroid hormone regulation studies, aiding in understanding metabolic processes and hormone synthesis. Its role in thyroid cancer monitoring is significant, as it helps in assessing tumor recurrence post-treatment. This protein is also used in educational settings for teaching endocrinology and immunology concepts.
