Radioimmunoassay

2003
Radioimmunoassay is often described in terms of the competition between a radiolabeled antigen (Ag*) and its unlabeled counterpart (Ag) for binding to a limited amount of specific antibody (Ab) (1). In most radioimmunoassays the reaction is allowed to proceed to equilibrium and thus, can be represented by Eq. (1). [Formula: see text].

Morphine: Radioimmunoassay

Science, 1970
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.

Barbiturates: Radioimmunoassay

Science, 1971
The development of a radioimmunoassay for barbiturate is described. The barbiturate is made antigenic by coupling it to a protein, bovine gamma globulin. The radioimmunoassay can measure as little as 5 nanograms of barbiturate.

Radioimmunoassay

Angewandte Chemie International Edition in English, 1976
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 ...
