1. 5 Recent advances in reproductive endocrinology are primarily due to the development of radioimmunoassay.

2. Plasma samples were collected to measure the renin-angiotensin system (RAS) activities and reactive oxygen species levels by radioimmunoassay, Chromatometry and ELISA

3. After treatment, the wet weight of prostate gland was detected, and the serum levels of testosterone (T) and dihydrotestosterone (DHT) were examined with radioimmunoassay method.

4. Up to 10% cash back  · The levels of cyclic GMP (cGMP) and cyclic AMP (cAMP) were assayed, using radioimmunoassay, in newt Blastemata cultured with and without insulin

5. Concentrations of prostaglandins of the E and F series were estimated by radioimmunoassay in cerebrospinal fluid (CSF) of 30 febrile patients (infants and adults) and of 19 afebrile, adult patients.

6. When the purified125J-α-Bungarotoxin-acetylcholine receptor complex was applied in a radioimmunoassay 80% of the Myasthenia gravis patients had acetylcholine receptor antibodies in contrast to none of the tested control persons.

7. Using a radioimmunoassay to measure the relative potencies of a wide range of chemically modified structures related to the H-type 2 human blood group determinant, evidence was accumulated that the binding of αLFuc(1→2)βDGal(1→4)-βDGlcNAc-OMe by the lectin I of Ulexeuropaeus involves a wedge-shaped amphiphilic surface which extends on one side of the molecule from the methoxy aglycon to OH-3 of the βDGal unit.

8. Plasma analyses included Cs (Cs radioimmunoassay IBL; normal 120–250 ng/ml), adrenocorticotropic hormone (ACTH) (ACTH-II IRMA; normal (10–50 pg/ml), glucose, and electrolytes determined as follows: preoperatively (8 a.m.); 1–6 h (60-min intervals) after surgery; pre-corticotropin-releasing hormone (CRH) (Corticobiss®:2 μg/kg i.v.) administration (1st postop. day at 8 a.m. and after 30, 60, 90, and 120 min. The study was completed with plasma analyses on postoperative days 2 and 3 (8 a.m.).
