Histamine is formed by decarboxylation of the amino acid histidine and is found both in plants and in animals, including man. In man it has important biologic functions. To assess the physiologic role of histamine, however, it is necessary to have a reliable and convenient method to determine its concentration in biologic fluids and tissue.

Radioimmunoassay of Glibenclamide
Diabetes, 1979A specific, sensitive, and simple radioimmunoassay was developed for the oral hypoglycemic drug glibenclamide, N-4-[2-(5-chloro-2-methoxy-benzamide)- ethyl]-benzenesulfonyl-N'-cyclohexylurea. Antiserum against glibenclamide was obtained from rabbits immunized with an antigen prepared by conjugating the diazonium salt of N-(p-amino-benzamidoethyl ...

A radioimmunoassay for progesterone
Steroids, 1972Abstract The need for a simple and fast quantitative method for progesterone with routine laboratory and clinical application motivated the development of a radioimmunoassay. Progesterone antibodies were produced in rabbits by immunization with a bovine serum albumin conjugate of 11α-hydroxyprogesterone hemisuccinate.

A radioimmunoassay of androstenedione
Steroids, 1973Abstract A dextran-coated charcoal radioimmunoassay for androstenedione (4-androsten-3, 17-dione) is reported which uses an anti-testosterone antiserum raised in sheep, against a testosterone-17-hemisuccinate-Bovine Serum Albumin conjugate. It is more sensitive and rapid than previously published double dilution, gas chromatographic and competitive ...

The development of a radioimmunoassay for morphine is described. The hapten morphine is made antigenic by coupling it to a protein at the phenolic group of the molecule. Extremely low concentrations of morphine (0.5 nanogram) can be measured by this assay procedure.

A radioimmunoassay for diphenylhydantoin
Clinica Chimica Acta, 1973Abstract A radioimmunoassay for the anticonvulsant compound diphenylhydantoin (DPH) has been developed. Antisera were prepared by immunizing animals with a DPH-chicken γ-globulin conjugate. The assay depends on the capacity of unlabelled DPH to compete with a known amount of [14C]DPH for the antibody-binding sites. The assay can detect as little as 0.

AbstractBiologically active substances are often effective in nanogram or even smaller quantities. Investigations of their mode of action therefore require highly sensitive microanalytical methods of detection. Chemical, chromatographic or spectrometric methods frequently lack the required sensitivity; it was only after the discovery of the ...
