Estrone, Direct RIA Kit [CE]

Radioimmunoassay for the Quantitative Determination ofEstronelevel in Human plasma or serum. The origin of plasma estrogens in women has been precisely studied by refined isotopic dilution techniques. In normal women, most plasma estradiol is derived from the ovary, where theca cells secrete androstenedion, which is then converted to estrone and then to estradiol by the granulosa cells. Estrone in the circulation is essentially bound to albumin. This is important in the interpretation of estrone
