General Description of Thyroid Peroxidase .
Thyroid peroxidase (TPO) is a transmembrane protein of 107kDa containing a heme prosthetic group. It is present as a dimer on the apical surface of thyroid follicular cells. TPO is the primary enzyme involved in thyroid hormone synthesis. Malignant thyroid tumors exhibit an anomaly in TPO resulting in lower affinity for anti-TPO. This antibody may aid in the differentiation between benign and malignant thyroid tumors.

Antibody (Suitable for clinical applications)

Sample Type: FFPE Patient Samples.
Tested Applications: IHC. Approved for In Vitro Diagnostic Procedures on FFPE tissues. For tissue collection recommendations, please see datasheet sent with product.

Thyroid Peroxidase Information for Pathologists


Thyroid peroxidase (TPO) is an enzyme involved in TH synthesis. It is expressed on the apical surface of thyroid folliular cells.

Common Uses By Pathologists:

Malignant thyroid tumors exhibit an anomaly in TPO resulting in lower affinity for anti-TPO. TPO staining may help differentiate between benign and malignant thyroid tumors. TPO staining is also useful for classification of solitary cold thyroid nodules in FNA cytology samples.

Limitations and Warranty

This antibody is manufactured in accordance with clinical good manufacturing practices in an ISO13485:2016 certified production facility. It is intended for multiple uses including in vitro diagnostic use and research use only applications. Please see vial label for expiration date. We strive to always deliver antibodies with a shelf life of at least two years.
