Triiodothyronine Radioimmunoassay

Triiodothyronine radioimmunoassay.

Highly specific antisera to triiodothyronine (T(3)) were prepared by immunization of rabbits with T(3)-bovine serum albumin conjugates. Antisera with T(3) binding capacity of up to 600 ng/ml were obtained. The ability of various thyronine derivatives to inhibit the binding of T(3-) (125)I to anti-T(3) serum was found to vary considerably. l-T(3), d-T(3) and several triiodoanalogues were potent ...

Rapid radioimmunoassay of triiodothyronine.

The method used in this report is based on the immunological production of a specific antisera to tnlodothyronine (T3) in rabbits. Conducted at 4 #{176}C, the radioimmunoassay requires three to five days to complete. Hoping to speed this assay, we investigated the influence of time, temperature, and pH. Incubation at 37 #{176}C and pH 8.0 for 30 mm did not deleteriously affect either precision,...

Radioimmunoassay of triiodothyronine in unextracted human serum.

Serum triiodothyronine (T-3) concentrations have been estimated by radioimmunoassay using unextracted serum. The serum T-3 concentrations have been shown to be similar in two separate European populations (0.76-1.67 ng/ml). Raised T-3 values have been observed in all subjects with hyperthyroidism. Low values are seen in hypothyroidism although there is some overlap with the normal range. There ...
