5β-Tetrahydrocortisol is an endogenous metabolite of hydrocortisone .1,2 It is also an intermediate in the biosynthesis of β-cortol .2 It is formed from cortisol by steroid 5β-reductase and is dehydrogenated by 20β-hydroxysteroid dehydrogenase (20β-HSD) to produce β-cortol in the liver.3,1,2 Urinary levels of 5β-tetrahydrocortisol have been used as a marker for cortisol production and are associated with metabolic syndrome in obese individuals.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。
