A 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 کاملRadioimmunoassay of erythropoietin: analytical performance and clinical use in hematology.
We report here the performance of a recently commercialized radioimmunoassay kit for determining erythropoietin (EPO) in serum or plasma. The lower detection limit of the method was 3 U/L. Precision, analyzed by the variation coefficients between different assay runs and in the same experiment, was always less than 10%; accuracy was assessed by recovery and dilution tests. In anemic patients (h...
متن کاملA 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 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 ...
متن کاملDEVELOPMENT OF A RAPID AND SENSITIVE RADIOIMMUNOASSAY FOR MEASUREMENT OF AFLATOXIN B 1 IN BIOLOGICAL SAMPLES
Aflatoxin B I (AFB) isa well known hepatocarcinogen in several animal species and probably a causative agent in human hepatocellular carcinoma. Humans are exposed to AFB by ingesting contaminated food. Aflatoxin contamination encountered in human foods is usually at low levels which is difficult to measure by chromatographic methods. Therefore in the present study we have developed an immun...
