Description

Asparaginyl-n-Acetylgalactosamine is a specialized glycosylated amino acid derivative, a key building block in glycobiology and glycoprotein research. This compound is crucial for studying and synthesizing complex carbohydrate structures, particularly O-linked glycans, due to its defined chemical linkage. It serves as an essential intermediate and reference standard for researchers and manufacturers in the pharmaceutical, biotechnology, and diagnostic sectors who require high-purity, well-characterized glycosylation precursors.

Application

• Glycoprotein Synthesis: As a critical building block for the chemical and enzymatic synthesis of O-linked glycopeptides and glycoproteins.
• Biopharmaceutical Research: Used in the development and characterization of therapeutic proteins, including monoclonal antibodies and other biologics where specific glycosylation patterns are vital for function and stability.
• Enzymology Studies: Serves as a substrate or inhibitor for glycosyltransferases, glycosidases, and other enzymes involved in carbohydrate metabolism and post-translational modification.
• Diagnostic Reagent Development: Employed in the production of standards and reagents for assays detecting specific glycan biomarkers or antibodies.
• Glycomics and Analytical Standards: Acts as a high-purity reference standard for mass spectrometry, HPLC, and NMR analysis to identify and quantify glycan structures in complex biological samples.
• Cell Biology & Immunology: Used to probe glycan-mediated cell signaling, adhesion, and immune recognition processes.
