    Product Description

    Taurochenodeoxycholic acid-d4 is intended for use as an internal standard for the quantification of taurochenodeoxycholic acid (TCDCA; Item No. 20275) by GC- or LC-MS. TCDCA is a taurine-conjugated form of the primary bile acid chenodeoxycholic acid (CDCA; Item No. 10011286).1 Serum levels of TCDCA increase approximately 5-fold within two hours and begin to decrease within four hours during an oral lipid tolerance test in humans.2 Serum levels of TCDCA are increased in patients with liver cirrhosis and may serve as a marker of disease progression.3

    WARNING This product is not for human or veterinary use.
