NON-RADIOMETRIC IMMUNOASSAYS [FLUOROIMMUNOASSAY (FIA) AND FLUOROMETRIC ENZYME IMMUNOASSAY (FEIA)] WITH RADIOIMMUNOASSAY (RIA) FOR EVALUATION OF ADRENAL FUNCTION IN NORMAL AND HYPERCORTISOLEMIC DOGS [PDF]

Ciência Rural, 2002
Non-radiometric immunoassays offer many advantages over radiometric assays, such as higher stability of kit compounds and absence of potential hazardous effects for users and environment. The comparison of cortisol measurements by fluoroimmunoassay (FIA)

Hair Testosterone and Cortisol Concentrations in Pre- and Post-Rut Roe Deer Bucks: Correlations with Blood Levels and Testicular Morphometric Parameters

Animals, 2018
The roe deer is a seasonally breeding species with a reproductive cycle regulated by endogenous rhythms and photoperiod-sensitivity. Sexually mature bucks show hormonal and testicular activation during the reproductive season, with a peak in the rut ...

Phytochrome Radioimmunoassay [PDF]

Plant Physiology, 1979
A phytochrome radioimmunoassay with a detection limit of about 2 nanograms has been developed. The radioimmunoassay does not suffer from the potential drawbacks of the commonly used spectral assay and requires less than 1 microliter of crude extract from dark-grown plants for quantitation of phytochrome.

Plasma testosterone and 11-ketotestosterone levels of male pacu Piaractus mesopotamicus (Cypriniformes, Characidae)

Brazilian Journal of Medical and Biological Research, 1997
The levels of testosterone (T) and 11-ketotestosterone (11-KT) of the South American pacu Piaractus mesopotamicus were determined by radioimmunoassay during two stages of the reproductive cycle, i.e., resting and maturation, and the gonadosomatic index ...
