Sialyl Lewis A, Sodium Salt is a tetrasaccharide carbohydrate antigen which functions to provide support for E-, L-, and P-selectin-dependent adhesion. Carbohydrates are now known to play a vital role in cell-cell recognition processes. Here, we describe an extended study enlightening the pharmacophores of 6’‐sulfo‐sialyl Lewis x and the successful development of a high‐affinity mimetic. Other Notes One of the most important carbohydrates for humans is the blood group antigen Sialyl Lewis X (SLeX). It is known to play a vital role in cell-to-cell recognition processes. 103, n. 45, 2006, pp. - Mechanism of Action & Protocol. Kannagi R. Carbohydrate antigen sialyl Lewis a (CA19-9) is the most frequently applied serum tumor marker for diagnosis of cancers in the digestive organs. Sialyl Lewis A, Sodium Salt is found biologically attached to O-glycans on cell surfaces. Nakagoe T(1), Fukushima K, Tanaka K, Sawai T, Tsuji T, Jibiki M, Nanashima A, Yamaguchi H, Yasutake T, Ayabe H, Arisawa K. Sialyl-Lewis x (s-Le x)-bearing species have been selected from plasma with the monoclonal antibody CHO-131.This antibody selects s-Le x antigen at points of branching in which the GlcNAc residue of s-Le x is coupled in a β-(1,6) linkage. Anti-sialyl Lewis A shows selective binding to M-cell apical membranes. Sialyl Lewis X (sLeX) also known as cluster of differentiation 15s (CD15s) or stage-specific embryonic antigen 1 (SSEA-1), is a tetrasaccharide carbohydrate which is usually attached to O-glycans on the surface of cells. The tetrasaccharide 6’‐sulfo‐sialyl Lewis x has been identified as a specific Siglec‐8 ligand in glycan array screening.
