Abstract
In this study, the production of anti-human thyroglobulin (Tg) monoclonal antibodies was attempted to detect Tg levels in serum and to study the localization of thyroid metastases in patients with thyroid-gland ablation. As a result four clones of hybridoma cell lines were obtained. By means of enzyme immunoassay (EIA) and immunohistochemical method, it was found that one of them, 2G4, produced a monoclonal antibody recognizing a malignant structural change of Tg and other three clones produced monoclonal antibodies recognizing not only the normal human Tg but also the malignant Tg. Our monoclonal antibody, 2G4, will be a hopeful reagent for the diagnosis in thyroid carcinoma.
