Abstract
Highly specific antisera to triiodothyronine (T3) were prepared by immunization of rabbits with T3-bovine serum albumin conjugates. Antisera with T3 binding capacity of up to 600 ng/ml were obtained. The ability of various thyronine derivatives to inhibit the binding of T3-125I to anti-T3 serum was found to vary considerably. l-T3, d-T3 and several triiodoanalogues were potent inhibitors of the reaction. Little inhibition of T3-125I binding was produced by l-thyroxine (T4) or other tetraiodo- analogues, thyronine or iodotyrosines. Chromatography of several T4 preparations indicated that most of their very slight activity could be ascribed to contamination with T3.
