Description

L-[Ul-13C6]Galactose is a stable isotope-labeled analog of the monosaccharide galactose, uniformly enriched with carbon-13 at all six carbon positions. This high-purity standard is critical for applications requiring precise metabolic tracing and quantification in complex biological systems. It is an essential research tool for scientists in pharmaceutical development, clinical diagnostics, and advanced biochemical research who require uncompromised isotopic purity and chemical stability for reliable data.

Application

• Metabolic Flux Analysis (MFA): Used as a tracer to map and quantify intracellular metabolic pathways in cell cultures, tissues, and microorganisms.
• Drug Metabolism and Pharmacokinetics (DMPK): Serves as an internal standard in LC-MS and GC-MS for the accurate quantification of galactose and its metabolites in biological fluids.
• Clinical Research & Diagnostics: Employed in developing and calibrating assays for inborn errors of metabolism, such as Galactosemia.
• Glycobiology & Glycomics: A precursor for the synthesis of isotopically labeled glycans, glycoproteins, and glycolipids for structural and functional studies.
• Nutritional Science: Facilitates studies on galactose absorption, utilization, and its role in human nutrition and lactose metabolism.
• Biomarker Discovery: Enables precise tracking of galactose-derived metabolites to identify novel biomarkers for disease states.
