Description

Bilirubin Ditaurine is a water-soluble, conjugated form of bilirubin, a key bile pigment. This compound is of significant value as a high-purity biochemical reference standard and a critical reagent in diagnostic research and development. It is primarily required by manufacturers and research institutions in the in-vitro diagnostic (IVD), clinical chemistry, and pharmaceutical analysis sectors for calibrating instruments and developing assays for liver function and metabolic disorders.

Application

• Clinical Diagnostic Calibrators & Controls: Primary standard for calibrating automated analyzers in bilirubin quantification tests.
• IVD Kit Manufacturing: Essential raw material for producing reagent kits used in liver function panels (LFTs).
• Biochemical Research: Used in studies of bilirubin metabolism, transport, and its role as an antioxidant.
• Pharmaceutical Analysis: Serves as a reference compound in method development and quality control for related pharmaceuticals.
• Enzyme Activity Assays: Substrate for studies involving enzymes like bilirubin oxidase.
• Educational & Reference Standards: High-purity material for academic teaching and commercial standard preparation.
