產品名稱：Estrone-3-Sulfate equine ELISA 產 地：Demeditec 產品貨號：DEV9933 產品規(guī)格：96 Tests 產品說明： Special remarks: Estrone-3-Sulfate (E3S) is the predominant conjugated estrogen during pregnancy. It is produced by the fetus, possibly in association with the endometrium in the pregnant mare. Different hormones are important for the complex events that occur during pregnancy in all mammals. In the mare these events include the maintenance of the corpus luteum function, formation of endometrial cups and development of secundary corpora lutea. Progesterone and PMSG (Pregnant Mare Serum Gonadotropine, eCG) and also free Estrogens, e.g. Estrone, are associated with these processes. It has been shown, that Estrone is rapidly conjugated after secretion and the ratio between conjugated and unconjugated estrogens is 100:1 in mare serum. The conjugated estrogenes, especially Estrone-3-sulfate, provide the opportunity to improve the accuracy of pregnancy diagnosis, to monitor the pregnancy and to distinguish whether the fetal development is normal or impaired. The diagnosis of embryonic death is usually made by using techniques of palpation of the uterus per rectum or ultrasound echography. The determination of Estrone-3-sulfate is an aid in the non-invasive diagnosis which allows a monitoring of the feto-placental unit during pregnancy. Only in mares with normal fetal development the values of Estrone-3-sulfate show a tremendous increase between day 75 and 100 of gestation. 上海玉博生物技術有限公司在為生命科學領域提供豐富的產品與信息資源方面處于****地位，公司提供的產品涵蓋了二十多個國家近五十萬種產品，而且產品的數(shù)量與信息在不斷的增長和更新，公司提供的產品能夠使生命科學工作者加快對生物化學，分子生物學，細胞生物學以及蛋白質組學研究的認知，以及分子診斷和臨床醫(yī)學領域的應用。
