Description

Taurine-15N is a stable isotope-labeled analog of the essential amino acid taurine, where the nitrogen atom is enriched with the 15N isotope. This product is critical for advanced research and analytical applications requiring precise metabolic and pharmacokinetic tracing. It is primarily utilized by scientists and manufacturers in the pharmaceutical, nutritional science, and biomedical research sectors for use as an internal standard in mass spectrometry and NMR spectroscopy.

Application

• Internal Standard for Mass Spectrometry (MS): Essential for the accurate quantification of taurine in complex biological matrices using LC-MS/MS and GC-MS methods.
• Metabolic Pathway Tracing: Used in NMR spectroscopy and stable isotope-resolved metabolomics to study taurine's role in bile acid conjugation, osmoregulation, and neurological function.
• Pharmaceutical Research & Development: Employed in drug metabolism and pharmacokinetic (DMPK) studies to track the absorption, distribution, metabolism, and excretion of taurine-containing compounds.
• Nutritional Science Research: Facilitates studies on taurine bioavailability, supplementation effects, and its functional role in energy drinks and infant formula.
• Biochemical Assay Development: Serves as a critical reference material in developing high-precision diagnostic assays and clinical testing protocols.
• Quality Control & Method Validation: Used by analytical laboratories to validate testing methods for taurine in raw materials and finished products, ensuring regulatory compliance.
