Thyroid-specific autoantibodies

EUROPLUS thyroid gland (monkey) and thyroglobulin antigen

Thyroid gland, unfixed and thyroglobulin BIOCHIP: antibodies against thyroid microsomes and thyroglobulin
  • Detection of antibodies against thyroid gland antigens.
  • Indications: Graves' disease, Hashimoto's autoimmune thyroiditis.
  • Initial dilution 1 : 10; conjugate class anti-human IgG, FITC-labelled.
  • Using unfixed thyroid tissue, two important thyroid-specific antibodies can be found: Autoantibodies against thyroid microsomes (MAb) give a granular staining in the cytoplasm of the follicle epithelium (target antigen: thyroid peroxidase, TPO). Autoantibodies against thyroglobulin (TAb) react with the colloid of all follicles of the thyroid tissue and cause a reticular fluorescence pattern.
  • With the thyroglobulin-coated BIOCHIP, autoantibodies against thyroglobulin (TG) can be confirmed monospecifically in one and the same test procedure.
  • This BIOCHIP Mosaic can be supplemented as required with further substrates, e.g. rat kidney, to achieve a differentiation of antibodies against thyroid microsomes from mitochondrial antibodies (AMA). For a serological diagnosis of autoimmune polyendocrinopathies, BIOCHIPs with frozen sections of pancreas, adrenal gland, ovary, testis and stomach can be added.
