(Synonyms: NSC 58792) 目录号 : GC30727An endogenous metabolite of cortisol
Cas No.:667-65-2
Sample solution is provided at 25 µL, 10mM.
β-Cortol is an endogenous metabolite of cortisol .1,2 It is formed from cortisol via the intermediate metabolite 5β-tetrahydrocortisol, which is dehydrogenated by 20β-hydroxysteroid dehydrogenase (20β-HSD) in the liver to produce β-cortol.2 Urinary levels of β-cortol have been used as a marker for cortisol production and are associated with metabolic syndrome in obese individuals.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 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。
