Description

A-Le(B)-Pentasaccharide CAS NO 128464-25-5 is a defined, high-purity carbohydrate derivative of significant interest in advanced biochemical research and development. This compound serves as a critical intermediate and reference standard for studying complex carbohydrate-protein interactions, particularly those involving selectins and other lectins. It is essential for researchers and manufacturers in the pharmaceutical and biotechnology sectors who are developing novel therapeutics, diagnostic tools, and vaccines that target specific glycan-mediated biological pathways.

Application

• Biopharmaceutical Research: As a key intermediate in the synthesis of complex oligosaccharides for drug discovery programs.
• Glycobiology Studies: Used as a precise reference standard or inhibitor in assays investigating cell adhesion, signaling, and immune response mechanisms.
• Diagnostic Development: Employed in the design and production of diagnostic kits and biosensors that detect specific carbohydrate-binding proteins.
• Vaccine Adjuvant Research: Investigated for its potential role in modulating immune responses as part of novel vaccine formulations.
• Enzymology: Serves as a substrate or inhibitor for glycosyltransferases, glycosidases, and other carbohydrate-processing enzymes.
• Chemical Synthesis: Acts as a sophisticated building block for the total or semi-synthesis of larger, more complex glycoconjugates and natural products.
