Sialyl-Lewis X - an overview ScienceDirect Topics

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 present invention relates to a method for diagnosing whether a subject may be at risk for or may suffer from cancer wherein (significantly) lower or (significantly) higher binding of a binding agent to a particular glycan structure of a biomarker glycoprotein compared to a control sample is indicative for said subject to be at risk for or to suffer from cancer. ctr tiffin roomWebGlycosylation is an important post-translational modification, giving rise to a diverse and abundant repertoire of glycans on the cell surface, collectively known as the glycome. ...
