Description

Sodium L-Lactate-13C3 Solution is a stable, isotopically labeled form of sodium lactate, where the three carbon atoms in the lactate moiety are the carbon-13 (13C) isotope. This product is essential as a high-purity internal standard and tracer for advanced quantitative analysis and metabolic pathway studies using techniques like mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy. It is primarily required by research institutions, pharmaceutical development labs, and analytical service providers engaged in metabolomics, pharmacokinetics, and stable isotope labeling studies.

Application

• Internal Standard for Quantitative Analysis: Used in LC-MS and GC-MS methods for the accurate quantification of lactate and related metabolites in complex biological matrices.
• Metabolic Tracer: Employed in in vitro and in vivo studies to trace glycolytic and gluconeogenic pathways, providing insights into cellular energy metabolism.
• NMR Spectroscopy: Serves as a chemical shift reference and a labeled substrate for 13C-NMR experiments to elucidate molecular structures and dynamics.
• Pharmaceutical Research: Utilized in drug metabolism and pharmacokinetics (DMPK) studies to track the fate of drug molecules and their metabolites.
• Diagnostic Assay Development: Acts as a critical component in calibrating and validating clinical diagnostic tests for lactate levels.
• Food & Beverage Science: Applied in research to study fermentation processes and metabolic activities of microorganisms.
