ω-Muricholic Acid-d4

ω-Muricholic acid-d4 (ω-MCA-d4) is intended for use as an internal standard for the quantification of ω-MCA (Item No. 20292) by GC- or LC-MS. ω-MCA is a murine-specific secondary bile acid.1,2 It is formed via enzymatic conversion of β-MCA (Item No. 20287) by a variety of intestinal microorganisms, including Clostridium, in rat and mouse gut.WARNING This product is not for human or veterinary use.
