title: Production and properties of novel human thyroid cancer specific monoclonal antibodies.
abstract: Monoclonal antibodies (TCM-7, -9 and -12) against human thyroid differentiated cancers were established by screening with human thyroid cancers, normal and benign thyroid tissue, and normal human serum protein. A monoclonal antibody (TCM-9) with strong specificity for human thyroid cancer but not for Graves' disease, adenoma or normal thyroid, was shown to recognize a 300 K protein but not to bind to native or mature human thyroglobulin. When TCM-9 was used in immunohistochemical staining tests on more than 30 types of non-thyroid lesions, no reactivity of TCM-9 was observed except with skin immature teratoma, lip squamous carcinoma and stomach adenocarcinoma, which revealed weak reactivities. TCM-9 also showed strong reactivity with two undifferentiated thyroid cancer cell lines and one tissue specimen. Thus TCM-9 is a novel monoclonal antibody against the thyroid cancer.
