Product Information CD61

Introduction:
CD61 antigen is expressed on platelets, megakaryocytes, monocytes, macrophages and endothelial cells. CD61 is the b3 integrin subunit which combines with CD41 to form the platelet glycoprotein IIb/IIIb (integrin aIIbb3) and with CD51 to form the vitronectin receptor (integrin aVb3) (1)


Application:
CD61, clone NaM28-7D6, can be applied in flow cytometry for analysis of blood and bone marrow samples or in immuno-histochemistry using cytospots or frozen tissue sections
CD61 antibodies are applied in the diagnosis of Glanzmann thrombastemia and leukemia. CD41/CD61 is the major integrin on platelets and is important for platelet adhesion and aggregation. The ligands for CD41/CD61 include fibrinogen, von Willebrand factor, fibronectin and thrombospondin. Binding to these ligands depends on the activation state of the platelets
CD51/CD61 acts as an activation-independent receptor for platelet attachment and spreading on vitronectin. Other ligands include fibrinogen, fibronectin, von Willebrand factor, laminin and thrombospondin. CD51/CD61 may also mediate cell-cell adhesion via an interaction with CD31. Antagonists of CD51/CD61 have been shown to inhibit tumor growth by disrupting angiogenesis (3)


Specifications:
CD61, clone NaM28-7D6 produces mouse IgG1 immunoglobulins directed against a 105 kDa antigen. Clone NaM28-7D6 was clustered at the Leucocyte Typing Workshop VI (2).


Performance Characteristics:
CD61, clone NaM28-7D6 monoclonal antibodies were analyzed by flow cytometry using a preparation of concentrated thrombocytes. The cytogram shows direct staining with 10 ml of CD61FITC and 100 ml cell sample
