DETAILS

Description (简体中文)
Application
β-雌二醇可用于研究细胞分化和转化(肿瘤发生)。
Reconstitution
要制备 20μg/mL 的储存液,可加入 1mL 无水乙醇,温和搅拌使之溶解,在搅拌下加入 49mL 无菌培养基。
Physical form
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
Biochem/physiol Actions
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。
