Radioimmunoassay for measurement of triiodothyronine in human serum.
A convenient, specific, precise, and reproducible radioimmunoassay system for measurement of triiodothyronine (T(3)) in human serum has been developed. The procedure compares the ability of standards and unknowns to compete with radioactive T(3) for binding sites on a T(3)-binding antiserum produced in rabbits by immunization with human thyroglobulin. The assay is set up in the presence of 250 ...
متن کاملRadioimmunoassay for measurement of thyroglobulin in human serum.
A specific and reproducible double antibody radioimmunoassay for the measurement of thyroglobulin (HTg) in human serum has been developed. Since antithyroglobulin autoantibodies combine with the [(131)I] HTg tracer, antibody-positive sera were rejected for measurement. Specificity is demonstrated in that thyroid analogous such as thyroxine (T(4)), triiodothyronine (T(2)) monoiodotyrosine (MIT) ...
متن کاملMeasurement of human dopamine-beta-hydroxylase in serum by homologous radioimmunoassay.
Human serum dopamine-beta-hydroxylase [3,4-dihydroxyphenylethylamine, ascorbate: oxygen oxidoreducatse (beta-hydroxylating), EC 1.14.17.1] levels have been determined in 52 samples with a newly devised radioimmunoassay that utilizes purified human enzyme and its specific antiserum. The values obtained were in excellent agreement (correlation coefficient r equals 0.98) with those obtained by mea...
متن کاملRadioimmunoassay of human serum thyrotrophin.
The double antibody radioimmunoassay of serum thyroid-stimulating hormone (TSH) allows measurement of circulating levels of the hormone in most normal subjects. The serum TSH level in normal subjects is 1.6 +/- 0.8muU/ml. Patients with non-toxic goitre and acromegaly have normal TSH levels. Values are always raised in hypothyroid patients (with primary thyroid disease) and are significantly low...
