5α,6α-epoxy Cholestanol is an oxysterol and a metabolite of cholesterol produced by oxidation.[1] 5α,6α-epoxy Cholestanol accumulates in MCF-7 breast cancer cells in a reactive oxygen species-dependent manner following tamoxifen and PBPE application and induces triacylglycerol biosynthesis by binding to liver x receptor β (LXRβ). [2] 5α,6α-epoxy Cholestanol levels are increased in rat aorta and mesenteric artery following orchidectomy, an effect that can be prevented by a DHA-supplemented diet.[1] Levels are also increased in post-mortem frontal and occipital cortex of patients with Alzheimer’s disease.

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。
