TPO Antibody (IHC)

Thyroid peroxidase (TPO) is located on the apical free surface of thyroid epithelial cells. It is directly involved in the oxidation of iodine, iodination of tyrosine and coupling of iodinated tyrosine in thyroid cells. It is an important factor in the synthesis of thyroid hormones. key enzymes. TPO is highly expressed in normal, proliferative and most benign tumor thyroid tissues, and its expression is significantly reduced in malignant thyroid tumors. The antibody can be used in the differential diagnosis of benign and malignant tumors in thyroid tissue.
