Description

D-Glucose, o-(n-Acetyl-.Alpha.-Neuraminosyl)-(23)-o-.Beta.-D-Galactopyranosyl-(14)-, Monoammonium Salt is a defined, high-purity carbohydrate derivative, specifically a sialylated trisaccharide in its ammonium salt form. This compound is of critical importance as a well-characterized reference standard and biochemical building block for advanced research and development. It is primarily needed by pharmaceutical, biotechnology, and diagnostic industries for applications in glycobiology, vaccine development, and the synthesis of complex glycoconjugates.

Application

• Glycobiology Research: Used as a key intermediate or reference standard for studying sialic acid-containing glycans, cell-cell interactions, and receptor-ligand binding.
• Pharmaceutical Development: Serves as a crucial starting material or precursor in the synthesis of complex carbohydrate-based drugs, vaccines, and therapeutic agents.
• Diagnostic Reagent Manufacturing: Employed in the production of high-specificity diagnostic kits and assays that target sialylated antigens or biomarkers.
• Enzymology Studies: Acts as a specific substrate for sialyltransferases, neuraminidases (sialidases), and other glycosyltransferases to study enzyme kinetics and inhibition.
• Bioconjugation & Probe Synthesis: Utilized for the chemical or enzymatic synthesis of labeled probes (e.g., fluorescent, biotinylated) for imaging and detection applications.
• Standards for Analytical Chemistry: Provides a certified reference material for HPLC, LC-MS, and other analytical methods to ensure accuracy in glycan analysis and quality control.
