A simple and rapid radioimmunoassay (RIA) without extraction or purification was developed for Total Estrogen (conjugated and unconjugated estrogen) in urine from normal men and nonpregnant women. Antiserum used to RIA was produced by immunizing rabbits with estriol-16 alpha-glucuronide (E3-16-G)-BSA

Biological research in pregnancy and perinatology, 5(2), 68-73 (1984-01-01)
The maternal peripheral serum level of estradiol-17 beta (E2), which reaches a peak a few weeks before delivery, may play a role in initiating delivery. In this study, the steroidal activity regulated by both the production and conjugation was estimated
H H Kay et al.
The Journal of reproductive medicine, 29(4), 222-226 (1984-04-01)
17 beta-estradiol (E2) and estriol-16-glucuronide in amniotic fluid from 87 patients (normal and stressed pregnancies) were studied with radioimmunoassays. Overall, amniotic fluid estradiol and estriol increased with gestation and paralleled the increase in the L/S ratio. Statistical correlations between amniotic
