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 sensitive and specific radioimmunoassay for rat and human serum ligandin was developed using antisera generated in rabbits by the injection of ligandin purified from liver. Because rat ligandin and human ligandin have no cross reactivity, radioimmunoassay systems for each of the serum ligandins were prepared. Highly purified ligandin labeled with125I

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.

Radioimmunoassay for immunoconglutinins
Journal of Immunological Methods, 1980A competitive radioimmunoassay for immunoconglutinin (IK) was developed using isolated antostimulated rabbit IK labelled with 125I and glutaraldehyde-fixed sheep erythrocytes coated with fixed complement (EAC). IKs in test sera of human or animal origin produced specific inhibition of uptake of [125I]IK onto EAC and this was quantitated by reference to

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].

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 ...

A RADIOIMMUNOASSAY OF THYROXINE
The Journal of Clinical Endocrinology & Metabolism, 1971ABSTRACT A simple, sensitive, specific and precise radioimmunoassay (RIA) for measurement of serum thyroxine (T4) is described. The RIA employs rabbit anti-thyroglobulin antiserum as the T4-binding protein. The precision, reproducibility and practicality of the RIA are comparable to those of competitive protein binding assay (CPBA) using serum TBG as ...

A RADIOIMMUNOASSAY FOR NEUROTENSIN
Clinical Endocrinology, 1981SUMMARYA specific radioimmunoassay for neurotensin has been developed with a sensitivity of 40 pg/ml. Neurotensin‐like immunoreactivity in human plasma shows characteristics similar to synthetic neurotensin on Sephadex G‐25 (f) gel chromatography.
