A radioimmunoassay for isoniazid.
A sensitive radioimmunoassay is described, for measuring isoniazid in therapeutic and subtherapeutic concentrations. This radioimmunoassay was used in an exploratory clinical study to measure, as a function of time, the concentration of this drug in plasma of patients receiving isoniazid therapy.
متن کاملA radioimmunoassay for erythropoietin.
We describe the development of a radioimmunoassay (RIA) for erythropoietin. Antisera were raised in rabbits with an impure human urinary erythropoietin preparation used as immunogen, but with pure human erytropoietin serving as the labeled antigen in the RIA and as a primary standard. The immunoreactivity of erythropoietin is not altered significantly by the mode of labeling with radioiodine, e...
متن کاملThyrocalcitonin and the response to parathyroid hormone.
1) In the absence of the thyroid gland, the infusion of parathyroid hormone leads to a prompt rise in plasma calcium and to prompt increase in the rate of excretion of calcium in the urine.2) In the presence of the thyroid gland, the parathyroid hormone-induced rise in plasma calcium is less marked; the rate of urinary calcium excretion falls initially and rises only after 20 to 30 hours of con...
متن کاملA conformational study of porcine thyrocalcitonin.
The structure of porcine thyrocalcitonin has been evaluated by circular dichroism, optical rotatory dispersion, infrared spectroscopy, and fluorescence. The degree of helical structure was estimated by circular dichroism (222 mp) and optical rotatory dispersion (233 mp) at the n + r* transition of the Q: helix. The optical activity at this transition suggests that thyrocalcitonin contains appro...
متن کاملA SPECIFIC, SENSITIVE, AND ONE-STEP EXTRACTION RADIOIMMUNOASSAY OF TESTOSTERONE FOR CLINICAL DIAGNOSIS
Testosterone was measured using antibodies raised against testosterone II B-carboxymethyl ether bovine serum albmin (T-IIB-CME-BSA) and testosterone 3- O-carboxymethyl oxime-BSA as immunogen. The antibody produced in this study exhibits minimal cross reactivity with the structurally related steroids specially 5 dihydrotestosterone (5 DHD. This allows to ommit the clean up step and measure ...
