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 ...

A radioimmunoassay for progesterone
Steroids, 1972Abstract The need for a simple and fast quantitative method for progesterone with routine laboratory and clinical application motivated the development of a radioimmunoassay. Progesterone antibodies were produced in rabbits by immunization with a bovine serum albumin conjugate of 11α-hydroxyprogesterone hemisuccinate.

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.

Journal of Endocrinology, 1978
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 for sulprostone
Prostaglandins, Leukotrienes and Medicine, 1982The development of a radioimmunoassay for measuring subnanogram amounts of the prostaglandin uterine stimulant, sulprostone (N-methanesulfonyl 16-phenoxy-omega-tetranor PGE2 carboxamide), is described. The 9-carboxymethoxime derivative of sulprostone was coupled to keyhole limpet hemocyanin to prepare the immunogen, and to tyramine to yield a precursor

A radioimmunoassay for metoclopramide
Journal of Immunological Methods, 1987A radioimmunoassay for the anti-emetic drug, metoclopramide, in the pmol range was developed. The immunogen was prepared by photolytic coupling of metoclopramide to bovine serum albumin. A crosslinking reagent, N-hydroxy-succinimidyl-4-azidobenzoate, was first reacted with serum albumin through nucleophilic substitution. Ultraviolet irradiation (lambda

Radioimmunoassay of Proteoglycans
Journal of Immunoassay, 1984Human articular cartilage proteoglycan monomers (PG) were purified and used for developing a radioimmunoassay. Its analytical sensitivity is 0.6 ng/tube and its clinical sensitivity is 20 microliter/tube for serum and 0.12 microliter/tube for synovial fluid.

Seminars in Nuclear Medicine, 1975
The powerful nuclear medicine tool of radioimmunoassay was very rapidly developed because of the favorable properties of insulin in such a procedure. The current method of insulin immunoassay in our laboratory is described, with emphasis on the details of the separation of bound and free using talc tablets; emphasis is also given to the correction for ...
