Monoclonal Mouse Purified E B IH FC
Sialyl Lewis X, also known as sialyl LeX and SLeX, is a tetrasaccharide carbohydrate that 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. Sialyl Lewis X is one of the most important blood group antigens and is displayed on the terminus of glycolipids that are present on the cell surface. The Sialyl Lewis X determinant, E-selectin ligand carbohydrate structure, is constitutively expressed on granulocytes and monocytes and mediates inflammatory extravasation of these cells. Resting T and B lymphocytes lack its expression and are induced to strongly express sialyl Lewis X upon activation. The Sialyl Lewis X determinant is expressed preferentially on activated Th1 cells but not on Th2 cells.
