Epipregnanolone is a neurosteroid and an active metabolite of the steroid hormone pregnenolone .1 It is enzymatically formed from pregnenolone via the intermediates progesterone and 5β-dihydroprogesterone in the placenta.2 Epipregnanolone inhibits spontaneous contractions in myometrial strips isolated from at-term pregnant women (IC50 = 156 ?M).3 Epipregnanolone (10 and 20 mg/kg) decreases operant alcohol self-administration in rats.4 Maternal plasma levels of epipregnanolone increase over the duration of pregnancy.

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。
