Description

3''-Sulphated Lewis X, Methyl Glycoside Sodium Salt (~90%) is a well-defined, synthetic carbohydrate derivative, specifically a sulfated trisaccharide glycoside. This compound is a crucial biochemical tool for studying carbohydrate-protein interactions, particularly those involving selectins and other sulfated glycan-binding proteins. It is primarily utilized by researchers and developers in the fields of glycobiology, immunology, and pharmaceutical discovery for use as a reference standard, enzyme substrate, or inhibitor in assay development.

Application

• Glycobiology Research: As a critical reference standard and probe for investigating sulfated glycan-mediated cell adhesion and signaling pathways.
• Enzyme Assay Development: Serving as a specific substrate or inhibitor for sulfotransferases, glycosidases, and lectins (e.g., selectins).
• Pharmaceutical Screening: Used in high-throughput screening (HTS) campaigns to identify novel anti-inflammatory or anti-metastatic drug candidates that target selectin-carbohydrate interactions.
• Diagnostic Reagent Component: Potential use in the development of diagnostic kits for diseases where sulfated Lewis X antigens are biomarkers.
• Bioconjugation & Probe Synthesis: Acts as a building block for the synthesis of more complex neoglycoconjugates, biotinylated probes, or microarray elements.
• Standards for Analytical Chemistry: Providing a qualified standard for HPLC, MS, or NMR analysis in quality control of related biopharmaceuticals.
