    Product Description

    Tauro-d4-deoxycholic acid is intended for use as an internal standard for the quantification of taurodeoxycholic acid (Item Nos. 44869 | 15935) by GC- or LC-MS. Taurodeoxycholic acid is a taurine-conjugated form of the secondary bile acid deoxycholic acid (Item Nos. 20756 | 18231).1 Taurodeoxycholic acid stimulates chloride ion secretion through calcium-activated chloride ion channels and cystic fibrosis transmembrane conductance regulator (CFTR) in Calu-3 airway epithelial cell monolayers when applied basolaterally.2 Serum levels of taurodeoxycholic acid increase approximately 5-fold within two hours during an oral lipid tolerance test in humans.1

    WARNING This product is not for human or veterinary use.
