A 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...
متن کاملA specific and sensitive radioimmunoassay for human choriogonadotropin.
A specific and sensitive radioimmunoassay for human choriogonadotropin (hCG) has been developed using rabbit antiserum to chemical analogs of beta subunit of human chorionic gonadotropin prepared by controlled reduction and S-alkylation of its disulfide linkages. The assay was highly specific for hCG as the binding of [125I]-hCG to the antibody was not affected by standard human lutropin, by hu...
متن کاملSensitive radioimmunoassay for digoxin in plasma and urine.
A reproducible and sensitive radioimmunoassay for digoxin in either serum, plasma or urine is described. Using 0.5 ml of serum or plasma, the assay sensitivity is 0.05 ng of digoxin/ml. The antiserum and tracer solutions employed are available in a kit sold in the United States. All other reagents were prepared in the laboratory. The assay allows measurement of digoxin in plasma or serum for 96...
متن کاملSensitive, specific radioimmunoassay for quantifying pergolide in plasma.
Pergolide, a synthetic ergoline with potent dopaminergic activity, is used to treat Parkinson disease. The low plasma concentrations of pergolide achieved during therapy complicate the development of a method for its analysis. Because radioimmunoassay successfully measures other structurally related ergolines in physiological fluids, we undertook the development of a radioimmunoassay of pergoli...
