Description

L-Tyrosine-13C is a stable isotope-labeled analog of the essential amino acid L-Tyrosine, where the carbon atom at the 13C position is enriched. This product is a critical tool for advanced research and development, enabling precise metabolic pathway tracing and quantitative analysis in complex biological systems. It is primarily utilized by pharmaceutical R&D teams, academic research institutions, and diagnostic manufacturers working in the fields of metabolomics, pharmacokinetics, and stable isotope labeling studies.

Application

• Biomedical Research & Metabolomics: Used as an internal standard or tracer for studying tyrosine metabolism, protein synthesis rates, and neurotransmitter (dopamine, epinephrine) production pathways.
• Pharmaceutical Development: Employed in drug metabolism and pharmacokinetic (DMPK) studies to track the fate of drug compounds and their metabolites in vivo.
• Clinical Diagnostics: Serves as a reference standard in mass spectrometry-based assays for the accurate quantification of tyrosine and related metabolites in biological samples.
• Nutritional Science Research: Applied in studies investigating amino acid absorption, utilization, and turnover in human and animal models.
• Isotope Labeling & Synthesis: Acts as a labeled building block for the synthesis of more complex 13C-labeled peptides, proteins, or other bioactive molecules.

Quality Control

Our L-Tyrosine-13C is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for chemical and isotopic purity, NMR for structural confirmation, and MS for isotopic enrichment verification. Certificates of Analysis (COA) detailing batch-specific results for identity, purity, and isotopic abundance are provided to ensure traceability and compliance with your research or production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed in a low-humidity environment to maintain stability and prevent degradation.
