Description

α-n-Acetylgalactosaminyl-(1-3)-[α-Fucosyl-(1-2)]-β-Galactosyl-(1-4)-β-n-Acetylglucosaminyl-(1-3)-β-Galactosyl-(1-4)-Glucose is a complex, defined oligosaccharide of significant interest in advanced biochemical research and development. This compound serves as a critical high-purity reference standard and synthetic intermediate for studying carbohydrate-protein interactions, cell signaling, and antigenic determinants. It is primarily utilized by pharmaceutical R&D teams, diagnostic developers, and academic research institutions focused on glycobiology, immunology, and the development of novel therapeutics and vaccines.

Application

• Biochemical Research Standard: Used as a high-purity reference compound for the study of glycosylation patterns, enzyme specificity (glycosyltransferases/glycosidases), and carbohydrate-mediated biological recognition.
• Glycoconjugate Synthesis: Acts as a key building block or precursor in the chemical and enzymatic synthesis of more complex glycoproteins, glycolipids, and neoglycoconjugates.
• Immunological Studies: Employed in research related to blood group antigens, host-pathogen interactions, and the development of carbohydrate-based vaccines and diagnostic reagents.
• Cell Biology & Diagnostics: Utilized in the development of assays and tools for probing cell surface receptors (lectins), cell adhesion processes, and biomarker discovery.
• Enzyme Substrate/Inhibitor: Serves as a specific substrate for characterizing the activity of glycosyltransferases or as an inhibitor in studies of carbohydrate-processing enzymes.
• Pharmaceutical Intermediate: Potential intermediate in the development of targeted therapeutic agents where specific carbohydrate motifs are essential for bioactivity.
