    Product Description

    Taurocholic acid-d4 (TCA-d4) is intended for use as an internal standard for the quantification of TCA (Item No. 16215) by GC- or LC-MS. TCA is a taurine-conjugated form of the primary bile acid cholic acid (Item No. 20250).1 Serum levels of TCA are decreased in patients with Crohn’s disease and those with ulcerative colitis with no extraintestinal manifestations but are increased in patients with ulcerative colitis accompanied by hepatobiliary disease.2

    TCA-d4 MaxSpec® standard is a quantitative grade standard of TCA-d4 (Item No. 21891) that has been prepared specifically for mass spectrometry and related applications where quantitative reproducibility is required. The solution has been prepared gravimetrically and is supplied in a deactivated glass ampule sealed under argon. The concentration was verified by comparison to an independently prepared calibration standard. The verified concentration is provided on the certificate of analysis. This TCA-d4 MaxSpec® standard is guaranteed to meet identity, purity, stability, and concentration specifications and is provided with a batch-specific certificate of analysis. Ongoing stability testing is performed to ensure the concentration remains accurate throughout the shelf life of the product. Note: The amount of solution added to the vial is in excess of the listed amount. Therefore, it is necessary to accurately measure volumes for preparation of calibration standards. Follow recommended storage and handling conditions to maintain product quality.

    WARNING This product is not for human or veterinary use.
