Estrone ELISA kits are assays designed to detect the weak estrogen hormone estrone. It is one of the main endogenous estrogens, and a minor female sex hormone. It is produced from androstenedione or testosterone via estradiol. It increases the synthesis of sex hormone-binding globulin (SHBG), thyroid-binding globulin (TBG), and other serum proteins and suppresses the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). It plays a role in the development of female reproductive tissues and secondary sexual characteristics. Visit the supplier page for more information about detection range and reactivity.
