Mouse Anti- Human CD106/VCAM- 1- FITC(100 tests)

CD106, also known as INCAM-1, is a 100-110 kDa vascular adhesion cell adhesion molecule-1 (VCAM- 1) that is member of the immunoglobulin superfamily. CD106 is expressed predominantly on cytokineactivated vascular endothelium but has also been identified on interfollicular dendritic cells, some macrophages and bone marrow stromal cells. Endothelial CD106 binds the integrins alpha₄beta₁ (CD49d/CD29, VLA-4) and alpha₄beta₇ and contributes to extravasation of lymphocytes, monocytes, basophils and eosinophils (but not neutrophils) from blood vessels, particularly at sites of inflammation. Unlike the beta₂ integrins, the CD106-VLA-4 interaction can mediate both the initial tethering and rolling of lymphocytes on endothelium as well as their subsequent arrest and firm adhesion. CD106 expressed on non-vascular tissues has been implicated in the interaction of hematopoietic progenitors with bone marrow stromal cells, B cell binding to follicular dendritic cells, costimulation of T cells, and embryonic development. The monoclonal antibody 1.G11B1 inhibits in vitro binding of lymphocytes and monocytes to VCAM-1 on stimulated endothelium.^1-4
