sLex pentasaccharide

Sialyl Lewis x pentasaccharide is a carbohydrate epitope that is a key ligand for selectins, a family of cell adhesion proteins. Its structure is a pentasaccharide containing sialic acid, fucose, galactose, and N-acetylglucosamine. This compound is involved in the rolling of white blood cells along the vascular wall during inflammation and is often overexpressed in various types of cancer, making it a potential diagnostic and therapeutic target.
