Estradiol (17β-estradiol) is the major estrogen secreted by the premenopausal ovary. Estrogens direct the development of the female genotype in embryogenesis and at puberty. In addition, estradiol is an important luteolytic agent in humans.1 Estradiol is synthesized from testosterone primarily in the ovarian granulosa cells and placenta, but small amounts can be produced in the adrenal gland.2,3 The conversion of testosterone to estradiol is accomplished by the aromatase system, which consists of 3 enzyme activities localized to the endoplasmic reticulum of the cells in these tissues.1,4 Plasma estradiol levels increase gradually between days 1-7 of the menstrual cycle followed by a sharp increase to a peak value of about 300 pg/ml on day 12 just prior to ovulation.1,5 Estradiol levels in most rodent samples are extremely low, rising to detectable levels only during the pro-estrus period and in pregnant females.

Needed but not supplied: Please download the kit booklet to verify if UltraPure Water (Milli-Q or equivalent) or any other components are needed for this assay.
