A two-step radioimmunoassay for free triiodothyronine in serum.
Using a high-affinity solid-phase-bound antibody (Ka = 1.2 X 10(11) L/mol), we have standardized a two-step radioimmunoassay for free triiodothyronine (FT3) in serum, based on immunoextraction. The method was validated by comparison with an equilibrium-dialysis procedure (r = 0.96) involving RIA of T3 in the dialysate standardized with the same antibody and by a commercial (Liso-Phase, Internat...
متن کاملRadioimmunoassay for serum myoglobin.
A column flow-through radioimmune assay for serum myoglobin has been developed. The assay uses antibodies to human or rhesus monkey myoglobin coupled to Sepharose by cyanogen bromide activation and myoglobin labeled by the Chloramine-T method. The labeled myoglobin is stable over two to three half-lives. Serum myoglobin levels were elevated when serum was taken up to 12 hours after myocardial i...
متن کاملDetermination of free thyroxine in serum by radioimmunoassay.
We describe a sensitive and specific radioimmunoassay for free thyroxine, directly determined in the diffusate obtained from equilibrium dialysis of serum. The intra- and interassay precisions were 7.5 +/- 0.27 and 9.1 +/- 0.58 ng/liter (mean +/- SD), respectively. The free thyroxine concentrations of normal persons and patients with thyroid disease were as follows: normal, 7.6 +/- 1.7; euthyro...
متن کاملPositive interference in Radioimmunoassay determination of serum total T3
Introduction: Determination of thyrotropin, total and free thyroxine and triiodothyronine are widely used as diagnostic methods for thyroid function evaluation. There have been numerous reports of interferences in thyroid hormone immunoassays. Herein, a prominent positive interference is reported for a radioimmunoassay kit of total triiodothyronine. Materials and Methods: In this study, a total...
متن کاملA radioimmunoassay for serum dehydroepiandrosterone.
Dehydroepiandrosterone (DHEA) and its sulfate ester, dehydroepiandrosterone sulfate (DHEAS) are the major adrenal C19 steroids in man. Concerning DHEAS many extensive studies have been reported using Zimmerman reaction and gas-liquid chromatography. Only a few papers, however, have appeared concerning DHEA. One of the causes of minute amount of information about DHEA was the complicated assay p...
