Description

α-Neu5Ac-[2->6]-β-Gal-[1->4]-β-Glcnac-[1->3]-β-Gal-[1->4]-Glc Sodium Salt is a complex, defined oligosaccharide derivative, specifically a sialylated tetrasaccharide, that serves as a critical biochemical tool and reference standard. Its precise structure makes it invaluable for studying carbohydrate-protein interactions, particularly those involving sialic acid and lectins. This high-purity compound is essential for researchers and developers in glycobiology, pharmaceutical R&D, and diagnostic assay development, where it is used to probe biological recognition events, develop inhibitors, and calibrate analytical systems.

Application

• Glycobiology Research: As a key substrate and reference standard for studying sialyltransferase and neuraminidase (sialidase) enzyme activity and specificity.
• Pharmaceutical Development: Used in the discovery and screening of novel therapeutics targeting influenza, bacterial infections, and cancer, where sialic acid-mediated recognition is a critical pathway.
• Diagnostic Reagent Manufacturing: Serves as a critical component or calibrator in immunoassays and lectin-based diagnostic kits for detecting pathogens or disease biomarkers.
• Biochemical Tool: Employed in surface plasmon resonance (SPR), microarray, and other biophysical techniques to characterize binding kinetics and affinity of lectins, antibodies, and viral hemagglutinins.
• Enzyme Inhibition Studies: Acts as a substrate analog for developing and testing inhibitors of glycosyltransferases and glycosidases.
• Cell Biology & Immunology: Used to modulate cell surface interactions and study the role of sialylated glycans in cell signaling, adhesion, and immune response.
