Description

Sialyl Lex Penta CAS NO 127923-85-7 is a complex, high-purity pentasaccharide carbohydrate derivative, a key structure in glycobiology research. This compound matters as a critical standard and reagent for studying cell-cell recognition, inflammation, and cancer metastasis processes mediated by selectin proteins. Research institutions and pharmaceutical developers in the fields of immunology, oncology, and diagnostic assay development require this well-defined glycan for their investigative and therapeutic programs.

Application

• Biomedical Research: Used as a high-purity standard and inhibitor in studies of selectin-mediated cell adhesion, leukocyte rolling, and inflammatory responses.
• Drug Discovery: Serves as a key building block or target epitope in the development of anti-inflammatory and anti-metastatic therapeutic candidates.
• Diagnostic Development: Employed in the design and calibration of diagnostic assays and biosensors for detecting specific carbohydrate-protein interactions.
• Glycoarray Fabrication: A vital component for printing functional glycan microarrays to profile protein binding specificity and discover new biomarkers.
• Enzymology Studies: Acts as a substrate or inhibitor for glycosyltransferases, glycosidases, and other carbohydrate-processing enzymes.
• Vaccine Research: Investigated as a potential synthetic antigen for cancer vaccines targeting tumor-associated carbohydrate antigens.
