CD61 (Integrin beta 3) Monoclonal Antibody (VI-PL2), FITC, eBioscience™, Invitrogen™

Description

Description: The VI-PL2 monoclonal antibody reacts with human CD61, also known as integrin beta 3 and GPIIIa. CD61 is a 90-110 kDa member of the beta integrin family expressed by a wide variety of cells, including leukocytes, platelets, endothelial and smooth muscle cells. CD61 binds non-covalently with the alpha integrins CD41 and CD51, to form the alpha IIb beta3 (CD41/CD61) and alpha v beta3 (CD51/CD61) complexes. These alpha beta heterodimers are capable of mediating a variety of cellular responses including adhesion, trafficking, proliferaton and differentiation. The CD41/CD61 integrin has been shown to be involved in platelet aggregation, and binds to fibrinogen, von Willebrand Factor (vWF) and fibronectin. The CD51/CD61 integrin binds to matrix proteins including vitronectin, fibronectin, vWF and fibrinogen, and has been shown to have a strong role in modulating the migration and survival of angiogenic endothelial cells. This VI-PL2 antibody has also been shown to crossreact with canine and several non-human primate species, including baboon, rhesus, and cynomologus monkey. Applications Reported: This VI-PL2 antibody has been reported for use in flow cytometric analysis. Applications Tested: This VI-PL2 antibody has been pre-titrated and tested by flow cytometric analysis of human platelets. This can be used at 5 μL (025 μg) per test.

CD61 (GPIIIa, ITGB3) is a glycoprotein found on megakaryocytes, platelets and their precursors. CD61 antigen plays a role in platelet aggregation and also as a receptor for fibrinogen, fibronectin, von Willebrand factor and vitronectrin. CD61 is a 105 kDa glycoprotein that associates with either the alpha 11b integrin (CD41) or the alpha V integrin (CD51) at the cell surface. CD61 is expressed on platelets and megakaryocytes in association with CD41, and on endothelial cells, monocytes, platelets and osteoclasts in association with CD51. CD61 is a receptor for fibrinogen, fibronectin, Von Willebrand Factor, vitronectin and thrombospondin. The CD61 protein product is composed of an alpha chain and a beta chain. A given chain may combine with multiple partners resulting in different integrins. CD61 is found along with the alpha IIb chain in platelets. Like other integrins, CD61 is known to participate in cell adhesion as well as cell-surface mediated signaling. Diseases associated with CD61 dysfunction include Glanzmann Thrombasthenia and Platelet type-16 Bleeding Disorder.
