Description

α-δ-Ua-[1->3]-Galnac-4S Sodium Salt is a chemically defined, sulfated carbohydrate derivative, specifically a glycosaminoglycan (GAG) oligosaccharide fragment. This compound is a critical high-purity biochemical tool for research into carbohydrate-protein interactions, enzymatic pathways, and glycobiology. It is primarily utilized by pharmaceutical R&D teams, academic research institutions, and diagnostic reagent developers for its role in studying sulfation patterns and biological recognition events.

Application

• Glycobiology Research: As a standard or substrate for studying sulfotransferase and sulfatase enzyme activity and specificity.
• Pharmaceutical Development: Investigation of carbohydrate-based drug candidates, particularly for targeting inflammation, coagulation, and viral entry mechanisms.
• Diagnostic Reagent Synthesis: Used in the development of assays and biosensors that detect specific carbohydrate-binding proteins or antibodies.
• Biochemical Standard: Serves as a reference material for the analysis and quality control of complex carbohydrate mixtures.
• Heparin/Heparan Sulfate Mimetics: Research into synthetic analogs of these biologically important GAGs for therapeutic applications.
• Cell Signaling Studies: Probing the role of specific sulfated glycan structures in cell-cell communication and growth factor binding.
