Sample solution is provided at 25 µL, 10mM.
2-methoxy Estrone is an active metabolite of the endogenous estrogen estrone .1 It is formed from estrone by catechol-O-methyltransferase (COMT). 2-methoxy Estrone inhibits the proliferation of isolated bovine brain-derived capillary endothelial cells (IC50 = 11.5 ?M).2 It increases the levels of 6-keto prostaglandin F1α in human umbilical vein endothelial cells (HUVECs) when used at concentrations of 0.001, 0.01, and 0.1 ?M.3 2-methoxy Estrone (0.5 mg/kg) reduces ovariectomy-induced increases in serum cholesterol in rats.4

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 saline,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。
3. 以上所有助溶剂都可在 GlpBio 网站选购。
