Used in research settings to detect and quantify thyroid peroxidase antibodies (anti-TPO) in human serum or plasma. This kit is essential for studying autoimmune thyroid diseases such as Hashimoto's thyroiditis and Graves' disease. By measuring anti-TPO levels, researchers can assess immune activity against the thyroid gland, aiding in the understanding of disease progression and immune response. The ELISA format allows for high-throughput screening with high sensitivity and specificity, making it a valuable tool in clinical research and laboratory investigations related to thyroid function and autoimmunity.
