The radioimmunoassay of buprenorphine
European Journal of Clinical Pharmacology, 1980Antisera to buprenorphine were obtained in rabbits immunised with 3-0-carboxymethylbuprenorphine and N-hemisuccinyl-norbuprenorphine conjugated to bovine serum albumin. Using the latter antiserum and tritium labelled buprenorphine a radioimmunoassay have good accuracy and precision was developed for concentrations as low as 50 picograms in 1 ml of ...

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

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 ...

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).

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 ...

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 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 ...

Radioimmunoassay of the A prostaglandins
Prostaglandins, 1972Antibodies to the A prostaglandins (PGA) were produced in rabbits immunized with a conjugate of prostaglandin E2 (PGE2) covalently linked to bovine serum albumin (BSA) by reaction with carbodiimide reagent. A radioimmunoassay was developed using dextran-coated charcoal to separate the free from antibody bound PGA1-3H.

A radioimmunoassay for orexin A has been developed. Anti-orexin A antiserum was raised in New Zealand white rabbits immunized with a conjugate of synthetic orexin A with bovine serum albumin. This antibody did not crossreact with orexin B, hypothalamic hormones, pituitary hormones, neuropeptides or gut hormones.
