Description

α-Neunac-[2->6]-β-Gal-[1->4]-β-Glcnac-[1->3][β-Gal-(1->4)-β-Glcnac(1->6)]-β-Gal-[1->4]-Glc CAS NO 118023-83-9 is a complex, high-purity oligosaccharide, specifically a branched hexasaccharide featuring N-acetylneuraminic acid (sialic acid) and N-acetylglucosamine residues. This compound is of significant value as a critical reference standard and research-grade biochemical for studying carbohydrate-protein interactions and cell signaling pathways. It is primarily required by biopharmaceutical R&D teams, diagnostic developers, and academic research institutions focused on glycobiology, immunology, and the development of novel therapeutics.

Application

• Glycobiology Research: Used as a precise substrate or inhibitor in studies of glycosyltransferase and glycosidase enzyme activities.
• Biopharmaceutical Development: Serves as a critical reference standard for the analysis and quality control of complex biologic drugs, including monoclonal antibodies and other glycoproteins.
• Diagnostic Reagent Manufacturing: Employed in the development of high-sensitivity diagnostic assays and biosensors that target specific carbohydrate epitopes.
• Cell Signaling & Immunology Studies: Applied to investigate the role of sialylated glycans in cell adhesion, immune recognition, and pathogen-host interactions.
• Enzyme Specificity Profiling: Acts as a defined substrate for characterizing the specificity of newly discovered carbohydrate-active enzymes.
• Synthetic Chemistry Intermediate: Used as a building block for the chemical or enzymatic synthesis of larger, more complex glycoconjugates and glycan arrays.
