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 ...

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.

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 ...

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 ...

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 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 ...

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.

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.

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 rhodopsin
Experimental Eye Research, 1980Abstract A radioimmunoassay for rhodopsin was devised using [125I]rhodopsin and antibody to purified bovine rhodopsin in a double antibody procedure that can quantify the concentration of this visual pigment when present in picomolar amounts. The method demonstrated a high degree of sensitivity, reproducibility, and specificity, and is applicable to ...
