Description

Disialyl-Lacto-n-Tetraose is a complex, branched oligosaccharide, specifically a sialylated tetrasaccharide. This compound is of significant interest in glycobiology and biomedical research due to its role as a key structural motif in human milk oligosaccharides (HMOs) and selectin ligands. It serves as a critical reagent for researchers and manufacturers in the life sciences sector, particularly those focused on glycan synthesis, biomarker discovery, and the development of nutritional or therapeutic products targeting gut health and immune modulation.

Application

• Glycobiology Research: Used as a standard, substrate, or intermediate in the study of glycosyltransferase activity, glycan biosynthesis pathways, and carbohydrate-protein interactions.
• Biomarker Development: Investigated as a potential biomarker or anti-adhesive therapeutic agent due to its role in cell-cell recognition and inflammatory processes.
• Nutritional Science: Serves as a reference compound for the analysis and quality control of complex oligosaccharides in infant formula and functional food products designed to mimic human milk glycans.
• Pharmaceutical Intermediates: Acts as a building block for the chemical or enzymatic synthesis of more complex glycoconjugates for drug discovery and vaccine development.
• Diagnostic Reagents: Employed in the development of assays and kits for detecting specific glycan-binding proteins or antibodies.
