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.

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.

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.

The evaluation of a radioimmunoassay of oxytocin is described. The method involved careful collection and transportation of blood at 4 °C, acidification of the plasma, extraction with Fuller's earth and radioimmunoassay using antisera raised in rabbits immunized against oxytocin conjugated to bovine serum albumin and 125I-labelled oxytocin.

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 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

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.

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 ...

A radioimmunoassay of androstenedione
Steroids, 1973Abstract A dextran-coated charcoal radioimmunoassay for androstenedione (4-androsten-3, 17-dione) is reported which uses an anti-testosterone antiserum raised in sheep, against a testosterone-17-hemisuccinate-Bovine Serum Albumin conjugate. It is more sensitive and rapid than previously published double dilution, gas chromatographic and competitive ...
