Description

Galnac-4S, Na is a high-purity, sodium salt derivative of N-Acetylgalactosamine (GalNAc), a critical monosaccharide building block. This compound is essential for the synthesis of advanced glycoconjugates, including complex oligosaccharides and glycopeptides used in cutting-edge research and therapeutic development. It is primarily utilized by researchers and manufacturers in the pharmaceutical, biotechnology, and diagnostic sectors for applications in glycobiology, drug discovery, and the development of targeted therapies.

Application

• Glycoconjugate Synthesis: A key precursor for the chemical and enzymatic synthesis of complex oligosaccharides, glycopeptides, and glycolipids.
• Pharmaceutical Research: Used in the development of glycan-based therapeutics, including antibody-drug conjugates (ADCs) and carbohydrate-based vaccines.
• Biochemical Tool: Serves as a substrate or inhibitor in enzymatic studies of glycosyltransferases and glycosidases to understand glycan biosynthesis pathways.
• Diagnostic Development: Employed in the creation of diagnostic assays and biosensors that rely on specific carbohydrate-protein interactions.
• Cell Biology Studies: Used to probe cell surface receptors, such as lectins, that recognize GalNAc motifs, aiding in studies of cell signaling and adhesion.
• Material Science: Incorporated into functionalized surfaces or polymers to create bioactive materials for tissue engineering and drug delivery systems.
