WebIt also recognizes Sialyl Lewis X with long carbohydrate attachments (Sialyl Lewis X-i). These antigens are expressed on human granulocytes, monocytes, small subsets of lymphocytes, some fetal tissues such as the fetal stomach, fetal colon, and fetal intestine, and a variety of cancer tissues.
Sialyl-Lewis X (sLeX) Ligand For Selectins
Sialyl Lewis (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. It is known to play a vital role in cell-to-cell recognition processes. It is also the means by which … See more Sialyl-Lewis X is a tetrasaccharide composed of a sialic acid, fucose and an N-acetyllactosamine.

WebOct 21, 2024 · The impact of glycosylation on cell behavior largely depends on the terminal portions of glycoconjugates. Examples of terminal structures include α2,3- and α2,6-linked sialic acids, polysialic acid, the AB0 blood group, and other fucosylated structures such as the sialyl Lewis x (sLe x) and the sialyl Lewis a (sLe a) antigens [1,2,3]. WebStructures of sialyl Lewis x (sLe x) and sialyl Lewis a (sLe a). Selectins bind to glycans with a terminal tetrasaccharide structure known as sialyl Lewis x/a. The core of the terminal tetrasaccharide is a disaccharide of galactose linked to N-acetylglucosamine (GlcNAc), either in α1,4 (sLe x) or α1,3 (sLe a) linkage. WebG.
