Urinary estrone conjugate and pregnanediol 3-glucuronide enzyme immunoassays for population research.
BACKGROUND Monitoring of reproductive steroid hormones at the population level requires frequent measurements, hormones or metabolites that remain stable under less than ideal collection and storage conditions, a long-term supply of antibodies, and assays useful for a range of populations. We developed enzyme immunoassays for urinary pregnanediol 3-glucuronide (PDG) and estrone conjugates (E1Cs...
متن کاملIdentification of anovulation and transient luteal function using a urinary pregnanediol-3-glucuronide ratio algorithm.
The sensitivity and specificity of a urinary pregnanediol-3-glucuronide (PdG) ratio algorithm to identify anovulatory cycles was studied prospectively in two independent populations of women. Urinary hormone data from the first group was used to develop the algorithm, and data from the second group was used for its validation. PdG ratios were calculated by a cycles method in which daily PdG con...
متن کاملDevelopment and evaluation of a rapid enzyme-immunoassay system for measurement of the urinary concentration of estrone-3-glucuronide in a female giant panda (Ailuropoda melanoleuca).
To detect estrus for reproductive management, and to determine the relationship between urinary estrogen and estrous behavior, in a female giant panda, we developed and evaluated a rapid enzyme immunoassay (EIA) system for urinary Estrone-3-glucuronide (E1G) using commercial reagents. The developed EIA system took only around 3 hours, including all procedures to obtain a result. It indicated go...
متن کاملMonitoring ovarian cycle activity via progestagens in urine and feces of female mountain gorillas: A comparison of EIA and LC-MS measurements.
Understanding the reproductive biology of endangered mountain gorillas (Gorilla beringei beringei) is essential for optimizing conservation strategies, determining any demographic impact of socioecological changes, and providing information for comparative studies of primates. Non-invasive techniques have been used to assess the reproductive function of many primates and the importance of valid...
متن کاملMonitoring the Reproductive Status of Dairy Cows by Urinary Pregnanediol Glucuronide
This study was undertaken with the aim to establish a reliable radioimmunoassay (RIA) system for urinary pregnanediol glucuronide (PdG) and to employ it for monitoring the reproductive status of dairy cows. Urine and blood samples were collected from the Holstein cows both pregnant and non-pregnant. The samples were then investigated for evaluating the relationship between progesterone (P4) in ...
