Description

Bilirubin ditaurate is a water-soluble, conjugated derivative of bilirubin, a key bile pigment. This compound is of significant value as a high-purity reference standard and critical biochemical reagent for diagnostic and research applications. It is primarily required by in-vitro diagnostic (IVD) manufacturers, clinical research organizations, and pharmaceutical R&D laboratories for calibrating analytical systems and studying liver function and bile metabolism.

Application

• Clinical Diagnostic Calibrators & Controls: Primary application as a precise reference material for calibrating bilirubin assays in automated clinical chemistry analyzers.
• In-Vitro Diagnostic (IVD) Kit Production: A key raw material for manufacturing reagent kits used to measure direct (conjugated) bilirubin levels in human serum or plasma.
• Biomedical Research: Used as a tool to study hepatobiliary function, jaundice, and the physiological role of bilirubin conjugates in cellular processes.
• Pharmaceutical Development: Serves as a standard in pharmacokinetic and metabolic studies for drugs affecting liver pathways.
• Quality Control Laboratories: Employed by third-party and in-house QC labs to verify the accuracy and precision of bilirubin testing methods.
• Enzyme Activity Studies: Used as a substrate in studies involving enzymes like bilirubin glucuronosyltransferase.
