A monoclonal antibody (LE4) specific for a thyrotropin (TSH) epitope shared by beta subunits of bovine (b), ovine (o), and human (h) TSH was obtained by immunization of mice with mixtures of purified bTSH and hTSH. LE4 also bound the beta subunits of bovine, ovine, and human lutropin (LH), and human chorionic gonadotropin (hCG) but not the beta subunits of porcine LH and TSH. Preliminary studies with deglycosylated (dg) bTSH and dg-hCG indicated that part of the epitope may be carbohydrate. Preincubation of LE4 with (/sup 125/I)bTSH inhibited the binding of the hormone to TSH receptor of bovine thyroid membranes in a dose-dependent manner. LE4 also inhibited TSH-induced mitogenesis of FRTL-5 cells. We conclude that LE4 binds to a site on the bTSH molecule that participates in high affinity binding of hormone to TSH receptor.
