Description

Disialylnonasaccharide-β-Pnp is a complex, synthetic oligosaccharide derivative featuring a para-nitrophenyl (Pnp) aglycon, widely used as a critical biochemical tool and reference standard. Its precise structure makes it invaluable for studying sialyltransferase activity, glycan biosynthesis, and carbohydrate-protein interactions. This high-purity compound is essential for researchers and developers in glycobiology, pharmaceutical R&D, and diagnostic assay development, where defined glycan structures are required for mechanistic studies and quality control.

Application

• Enzyme Substrate for Sialyltransferases: Acts as a specific acceptor substrate in assays to measure the activity and kinetics of α2,3- and α2,6-sialyltransferases.
• Glycobiology Research: Serves as a key intermediate or standard for synthesizing and analyzing complex multi-antennary N-linked glycan structures.
• Pharmaceutical Development: Used in the research and quality control of biopharmaceuticals, particularly monoclonal antibodies and other glycoproteins, to understand glycosylation patterns.
• Diagnostic Reagent Manufacturing: Employed in the development of enzymatic diagnostic kits for detecting specific glycosyltransferase activities related to disease states.
• Ligand Binding Studies: Utilized to investigate the binding specificity of lectins, antibodies, and other glycan-binding proteins (GBPs).
• Biochemical Tool Compound: Provides a well-defined, complex oligosaccharide for use as a positive control or calibration standard in analytical techniques like HPLC and MS.

Quality Control

Every batch of Disialylnonasaccharide-β-Pnp is manufactured under controlled conditions and undergoes rigorous analytical testing to ensure identity, purity, and consistency. Our quality system is designed to meet the exacting standards of research and pharmaceutical applications. A comprehensive Certificate of Analysis (COA) detailing purity (by HPLC), identity confirmation (by NMR/MS), and other critical parameters is provided with each shipment to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a desiccated environment. This product is hygroscopic (moisture-sensitive) and light-sensitive. Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake.
