Description

4-Pentenyl O-6-deoxy-α-L-galactopyranosyl-(1-2)-O-β-D-galactopyranosyl-(1-3)-O-2-(acetylamino)-2-deoxy-β-D-galactopyranosyl-(1-3)-O-α-D-galactopyranosyl-(1-4)-O-β-D-galactopyranosyl-(1-4)-β-D-glucopyranoside is a complex, well-defined oligosaccharide derivative that serves as a critical intermediate and reference standard in advanced biochemical research. This compound is essential for investigating carbohydrate-protein interactions, particularly in the study of blood group antigens, bacterial adhesion, and cell signaling pathways. It is primarily utilized by research institutions, diagnostic developers, and pharmaceutical companies engaged in glycobiology, immunology, and the development of novel therapeutics and vaccines.

Application

• Glycobiology Research: Used as a high-purity substrate or inhibitor to study enzyme kinetics, glycosyltransferase activities, and carbohydrate-mediated biological processes.
• Immunological Studies: Serves as a defined antigen for probing antibody specificity, investigating host-pathogen interactions, and developing serological assays.
• Diagnostic Development: Acts as a key component in the formulation of calibration standards and reagents for diagnostic kits targeting specific carbohydrate epitopes.
• Pharmaceutical R&D: Employed as a building block or intermediate in the synthesis of complex glycoconjugates for vaccine development and targeted drug delivery systems.
• Biomarker Discovery: Utilized in microarray and surface plasmon resonance (SPR) platforms to profile binding specificities of lectins and other carbohydrate-binding proteins.
• Reference Standard: Provides an analytical standard for quality control and method validation in the production of related oligosaccharides and glycoconjugates.
