16-Ketoestradiol is an active metabolite of the endogenous estrogen estrone .1 It is formed from estrone via an estriol or a 16-epiestriol intermediate by oxidation of the C-16 hydroxyl. 16-Ketoestradiol binds to estrogen receptor α (ERα) and ERβ with IC50 values of 112.2 and 50.1 nM for the human receptors, respectively.2 Intravaginal administration of 16-ketoestradiol increases vaginal epithelial thickness, stratification, and cornification in mice, indicating antiestrogenic activity.3

工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL ddH2O，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
