Description: The eBioMR106 monoclonal antibody reacts with rat CD106 (Vascular Cell Adhesion Molecule-1, VCAM-1), a 110 kDa transmembrane glycoprotein expressed by myeloid lineage and bone marrow stromal cells. Endothelial cells constitutively express low levels of CD106 and further upregulate VCAM-1 upon cytokine stimulation. CD106 binds to integrin α4β1 (VLA-4, CD49d/CD29) and Integrin α4β7 (LPAM-1) and these interactions in the bone marrow and thymus are important for early lymphocyte and myeloid development. Cytokine-mediated upregulation of CD106 on endothelial cells suggests a role for this antigen in the inflammatory response.
