Thyroglobulin (non-recombinant)
Diseases:
Autoimmune Thyroiditis (e.g. Graves Disease, Hashimoto Thyroiditis)
Thyroglobulin (TG) represents one of the main autoantigenic targets in autoimmune thyroid disease of humans. TG is a large globular dimeric glycoprotein with a total molecular weight of 660 kDa, which occupies a key precursor role in the biosynthesis of the thyroid hormones. Approximately 75% of the total protein content of the thyroid follicle consist of TG.
DIARECT produces native human thyroglobulin.
TG autoantibodies of IgG type have a prevalence of 80-85% in patients with Hashimoto thyroiditis and also a lower prevalence of 30-80% in patients with Graves disease.

在80-85%的桥本氏甲状腺炎,以及30-80%Grave‘s病患者中能检测到IgG型的TG自身抗体。
