Description

Galactopyranosyl(1-4)Acetylglucosaminyl(1-3)Acetylgalactosamine is a defined, high-purity oligosaccharide derivative, a key building block in glycobiology research and development. This compound is essential for studying and synthesizing complex carbohydrate structures found in glycoproteins and glycolipids, which are critical for cellular recognition and signaling processes. It serves as a vital intermediate for researchers and manufacturers in the pharmaceutical, diagnostic, and life science sectors who require precise and reliable glycosylation reagents.

Application

• Glycoconjugate Synthesis: A crucial intermediate for the chemical and enzymatic synthesis of complex oligosaccharides, glycopeptides, and glycolipids.
• Pharmaceutical Research: Used in the development of carbohydrate-based vaccines, drug candidates, and therapeutic agents targeting specific cell-surface receptors.
• Biochemical Tool: Serves as a standard, substrate, or inhibitor in enzymatic assays to study glycosyltransferase and glycosidase activities.
• Diagnostic Development: Employed in the creation of diagnostic assays and biosensors that rely on specific carbohydrate-protein interactions.
• Cell Biology Studies: Utilized to probe and modulate cell-surface interactions, adhesion, and signaling pathways mediated by glycan structures.
• Neoglycoconjugate Production: Acts as a starting material for attaching defined carbohydrate epitopes to carriers like proteins or polymers for immunological studies.
