    Product Description

    Tauro-d4-ursodeoxycholic acid (TUDCA-d4) is intended for use as an internal standard for the quantification of TUDCA (Item Nos. 20277 | 9003379) by GC- or LC-MS. TUDCA is a taurine-conjugated form of the secondary bile acid ursodeoxycholic acid (Item No. 15121).1,2 TUDCA is found in small quantities in human bile but at a higher concentration in the bile of black bears.2 It demonstrates anti-apoptotic activity in rodent models of tauopathy, Huntington's disease, ischemic brain injury, and retinal disorders.2,3
