产品说明

应用

β-雌二醇已用于:

  • 牛卵丘卵母细胞复合体(COC)的体外成熟
  • 作为可用作对照培养基的体外成熟培养基(IVM)中的一种补充剂
  • 雌激素诱导试验

包装

250 mg in glass bottle
1, 5, 25, 100 g in glass bottle

生化/生理作用

由绝经前卵巢分泌的主要雌激素。雌激素在胚胎形成中以及在青春期,通过调控基因转录,并因此调控蛋白合成,从而指导女性表型的发展。它还可诱导促性腺激素的生成,继而诱导排卵。暴露于雌二醇将增加乳腺癌的发病率以及增加增生。

产品说明

一般描述

β-雌激素或雌激素-17 β (E2)主要由卵巢中排卵前的大卵泡分泌。另外,雌激素可从含有胆固醇合成雄激素的胆固醇中从头合。芳香化酶酶(P450arom)对雄激素芳香化,可产生β-雌激素。

应用

β-雌二醇已用于:

  • 用作培养乳腺肿瘤细胞的杜氏改良Eagle培养基(DMEM)的成分
  • 用作测试神经保护作用的雌激素化合物
  • 用作培养卵母细胞的199培养基成分

β-雌激素可用于研究细胞分化和转化(致瘤性)。

包装

1, 5 g in glass bottle

生化/生理作用

由绝经前卵巢分泌的主要雌激素。雌激素在胚胎形成中以及在青春期,通过调控基因转录,并因此调控蛋白合成,从而指导女性表型的发展。它还可诱导促性腺激素的生成,继而诱导排卵。暴露于雌二醇将增加乳腺癌的发病率以及增加增生。
β-雌激素(E2)是女性绝经前的主要激素,对于男性精子发生、精子成熟和运动至关重要。培养骨髓干细胞(BMSC)具有合成E2的能力,可用于治疗雌激素缺乏症。它通过雌激素受体(ER)α和ERβ介导生理机能。

外形

室温下为粉末状;分成小份冻存,以避免使用时反复冷冻/解冻

重悬

制备20 μg/ml储备溶液,在1 mβ-雌二醇中加入1 ml无水乙醇;轻轻旋转溶解;混合时加入49毫升无菌培养基。
