anti-CD11c mouse monoclonal, EBS-CD-011, purified

Integrin ?X (CD11c, leukocyte surface antigen p150/95, CR4, Axb2) is a type 1 transmembrane protein that traditionally combines with ?2 chain to form a leukocyte-specific integrin known as inactivated-C3b (iC3b) receptor 4 (CR4). Integrin ?X /?2 shares similar properties of the Integrin ?M/?2 in mediating adherence of neutrophils and monocytes to stimulated endothelial cells and in phagocytosis of complement coated particles. Abnormal expression of Integrin ?X is characteristic of hairy cell leukemia (HCL) and is dependent upon activation of proto-oncogenes Ras and JunD. Integrin ?X is present on dendritic cells, macrophages and NK-cells. Upon activation, DCs present in skin (Langerhans cells_, lining of nose, lung, stomach, intestine and blood can migrate to lymphoid tissues and interact with T and B-cells to initiate and shape the immune response. Positive control: Human dendritic cells. Human lymph node and tonsil.
