Description

n-Acetylgalactosaminyl-1-4-n-Acetylglucosamine is a specialized disaccharide derivative of N-acetylglucosamine, a fundamental building block in glycobiology. This compound matters as a crucial intermediate and reference standard for the synthesis and analysis of complex oligosaccharides and glycoconjugates. It is primarily needed by research institutions and biopharmaceutical companies engaged in carbohydrate chemistry, glycomics research, and the development of novel therapeutic agents and diagnostic tools.

Application

• Glycobiology Research: Serves as a key intermediate and building block for the chemical and enzymatic synthesis of complex oligosaccharides and glycans.
• Pharmaceutical Development: Used in the research and development of carbohydrate-based drugs, vaccines, and diagnostic reagents.
• Enzyme Substrate & Inhibitor Studies: Acts as a substrate or inhibitor for glycosyltransferases, glycosidases, and other carbohydrate-processing enzymes to study their function and mechanism.
• Biomarker Research: Employed as a standard in analytical techniques like HPLC and MS for the identification and quantification of specific glycan structures in biological samples.
• Cell Biology: Utilized in studies of cell surface recognition, cell signaling, and intercellular communication mediated by carbohydrate-protein interactions.
• Reference Standard: Provides a high-purity chemical standard for quality control and method validation in analytical laboratories.
