Application Abreviews Notes
IHC-P Use at an assay dependent concentration. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.

(heat to 98 degrees C, allow to cool for 10-20 minutes)


IP Use at an assay dependent concentration.
WB Use at an assay dependent concentration. Predicted molecular weight: 103 kDa.


  • Function

    Iodination and coupling of the hormonogenic tyrosines in thyroglobulin to yield the thyroid hormones T(3) and T(4).
  • Pathway

    Hormone biosynthesis; thyroid hormone biosynthesis.
  • Involvement in disease

    Note=An alternative splicing in the thyroperoxidase mRNA can cause Graves' disease.
    Defects in TPO are the cause of congenital hypothyroidism due to dyshormonogenesis type 2A (CHDH2A) [MIM:274500]; also called genetic defect in thyroid hormonogenesis 2A or thyroid hormone organification defect II. CHDH2A is due to defective conversion of accumulated iodide to organically bound iodine. The iodide organification defect can be partial or complete.
  • Sequence similarities

    Belongs to the peroxidase family. XPO subfamily.
    Contains 1 EGF-like domain.
    Contains 1 Sushi (CCP/SCR) domain.
  • Post-translational

    Heme is covalently bound through a H(2)O(2)-dependent autocatalytic process. Heme insertion is important for the delivery of protein at the cell surface.
    Cleaved in its N-terminal part.
  • Cellular localization

    Membrane and Cell surface.

  • ab109383, at a 1/100 dilution, staining Thyroid Peroxidase/TPO in paraffin-embedded Human thyroid gland tissue

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab109383).

    Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
