12-keto Lithocholic acid is a metabolite of the secondary bile acid deoxycholic acid .1,2 Fecal levels of 12-keto lithocholic acid are elevated in rats fed a diet supplemented with cholic acid or DCA compared with rats fed a control diet or a diet supplemented with cholesterol , hyodeoxycholic acid , or lithocholic acid .2 12-keto Lithocholic acid activates the human pregnane X receptor (PXR; EC50 = 31.3 μM in a cell-based transactivation assay).3 12-keto Lithocholic acid levels are increased in duodenal bile from patients with type 2 diabetes.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。
