17 Beta Estradiol ELISA Kit
INTENDED USE
Human 17 beta estradiol ELISA kit is a reliable quantitative procedure for measuring 17-beta estradiol (17β-estradiol, 17 beta estradiol, 17b-diol) in human serum or plasma samples. This assay has a minimum sensitivity detection limit of 8.68 pg/ml.
BACKGROUND
17 beta estradiol (17β-estradiol, 17b-diol or 17-beta estradiol) is a sex hormone which represents the most important natural-estrogen in humans. It has a major role in reproduction and sexual functioning, there is also evidence to indicate that it can affect many other organs which include bone structure. In females, it is known to act as a growth hormone for tissue that are involved in the reproductive organs and in males it is involved with fertility. The measurement of estradiol levels can be used to evaluate fertility, monitor the ovarian follicular function during the induction phase of ovulation and detect any possible menstrual irregularities that may exist.
In plasma only a small faction is free (the biologically active form) which is approx. 1-3% whereas majority of it is found is bound to sex hormone binding globulin (SHBG) or albumin. It is only the free form that represents the active molecule during endocrine regulation. It is involved with some types of cancers such as; uterine lining, breast and many benign gynaecologic conditions (leiomyomata uteri, uterine bleeding and endometriosis).
