Description

O-6-Deoxy-α-L-galactopyranosyl-(1-2)-O-β-D-galactopyranosyl-(1-4)-O-2-(acetylamino)-2-deoxy-β-D-glucopyranosyl-(1-3)-O-[O-β-D-galactopyranosyl-(1-4)-2-(acetylamino)-2-deoxy-β-D-glucopyranosyl-(1-6)]-O-β-D-galactopyranosyl-(1-4)-D-glucose is a complex, high-purity oligosaccharide of significant interest in advanced biochemical research and development. This compound serves as a critical reference standard and building block for studying carbohydrate-protein interactions, particularly in glycobiology and immunology. It is essential for researchers and manufacturers in the pharmaceutical, diagnostic, and life science sectors who require well-defined, structurally precise glycans for vaccine development, biomarker discovery, and the synthesis of novel glycoconjugates.

Application

• Glycobiology Research: Used as a reference standard and substrate for studying enzyme specificity, glycosylation pathways, and carbohydrate-mediated biological recognition.
• Pharmaceutical Development: Serves as a key intermediate or active component in the research and synthesis of carbohydrate-based vaccines, including anti-cancer and anti-bacterial vaccines.
• Diagnostic Reagents: Employed in the development of diagnostic kits and assays for detecting specific antibodies or lectins that recognize complex oligosaccharide structures.
• Biomarker Discovery: Utilized in glycan array technology to profile serum antibodies and discover disease-specific glycan biomarkers.
• Enzymology Studies: Acts as a specific substrate for glycosyltransferases, glycosidases, and other carbohydrate-active enzymes to elucidate their function and mechanism.
• Synthesis of Glycoconjugates: Provides a defined oligosaccharide moiety for the chemical or enzymatic synthesis of glycoproteins, glycolipids, and neoglycoconjugates.
