Immunoassay Test Kit ESTRADIOL E2 for Automatic Immunoassay Analyzer In Fertility/Hormone

Estradiol (E2) is an important indicator to judge hormone disorders,  and mainly used to diagnose adolescence endocrine disorders  (precocious puberty, stunted growth, etc.), amenorrhea, or to  evaluate ovarian function of menstrual abnormalities and so on.

Estradiol (E2) is a kind of steroid hormone containing 18 carbon  atoms, with a molecular weight of 272.4 Daltons. It is the most  effective natural estrogen produced mainly by placenta and  Graffian follicle in female ovaries, and a small amount is produced  by adrenal gland and testis. After Estradiol is secreted into the  blood circulation, 98% binds with of the sex hormone binding  globulin (SHBG), while a small amount binds with other serum  proteins (such as albumin). Only a small part in free form or  combined form enters into the blood circulation. The physiological  function of estradiol is primarily to bind with estrogen receptors,  form complex, trigger and achieve some appropriate responses in  the target. These targets include the follicles, uterus, breast,  vagina, urethra, hypothalamus, pituitary, and in the liver and skin in  a small amount.
