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 ...
متن کاملRapid 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,...

متن کاملSteroid radioimmunoassay--effect of shortened incubation time on specificity.
Use of a briefer incubation interval in several steroid radioimmunoassays markedly increases cross reactions with some closely related steroids. The dissociation rates of the various steroid/antibody complexes play a critical role in determining the specificity of the antiserum, and the maximum specificity of an antiserum will be exploited only if it is incubated to equilibrium. The commonly us...
متن کاملRadioimmunoassay 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 ...
