Abstract The radioimmunoassay for glucagon has established the hormonal identity of this factor and exposed broad areas of its physiology and pathophysiology. While the ultimate importance of glucagon in man remains to be determined, there is little doubt that this previously unexplored area of endocrinology has been one of the major beneficiaries of

Radioimmunoassay of polyacrylamide
Experientia, 1978Antiserum to polyacrylamide has been produced in rabbits. It can be used in a sensitive radioimmunoassay for quantitation of polyacrylamide at very low concentrations. This novel approach to the analysis of a synthetic, biologically inactive, hydrocarbon polymer has potentially widespread implications, for example, in the downstream measurement of ...

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.

ABSTRACT A number of radioimmunoassay systems have been developed for quantitation of a variety of steroid hormones. Suitable antisera were obtained by immunizing rabbits with steroid derivatives conjugated at various positions to bovine serum albumin. The specificity of the antisera varied directly with the position of conjugation.

Radioimmunoassay for reserpine
Life Sciences, 1976Abstract Antisera against reserpine have been developed in rabbits immunized with reserpine conjugated to bovine serum albumin. These antisera were used in a radioimmunoassay procedure for reserpine. No appreciable cross-reactivity was observed either with reserpine metabolites or with other drugs commonly used in conjunction with reserpine for the ...

Radioimmunoassay of Angiotensin
Nature, 1968HABER et al.1 showed that antibodies elicited in rabbits by copolymers of angiotensin with poly-L-lysine can be used for radioimmunoassay of angiotensin. The following are details and some results of the method we have developed. Comparing the binding affinity of three different rabbit antisera to Val5-angiotensin II amide (‘Hypertensin’, Ciba) and ...

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.

Abstract A sensitive and specific radioimmunoassay has been developed for rat ligandin, capable of measuring this protein in the manogram range. The assay employs [125I] ligandin prepared by the chloramine-T method and rabbit antiserum to rat ligandin, with a double antibody method of separating antibody-bound from free ligandin.

Several sensitive radioimmunoassay systems for secretin have been developed and reported1–6. The development of these assay systems depended upon the generation of a specific secretin antiserum and the iodination of secretin (natural porcine secretin, synthetic secretin or a tyrosyl derivative of secretin).
