Sialyl-Lewis is important in leukocyte tethering and rolling. Leukocytes move through the blood stream and then tether themselves to the endothelial wall and roll along the endothelial tissue to determine if they want to leave the bloodstream to get to necessary tissue. Sialyl-Lewis is a necessary partner for the three selectins that bind the leukocyte and endothelial cells. When sialyl-Lewis is part of an O-glycan and attached to CD34 it can then bind to L-selectin. For the binding t… WebThe 100 synthetic glycans featured in the Glycan Array 100 are the most frequently identified structures showing important binding function in the literature.
