Description: The 2C9.G3 (HMb3-1) monoclonal antibody reacts with mouse and rat CD61, also known as the integrin beta3. CD61 is expressed by activated T cells, granulocytes, and platelet. CD61 associates non-covalently with two integrin alpha subunits; alphaV (CD51) to form Vitronectin Receptor and alphaIib (CD41) to form gpIIb/IIIa. These heterodimeric complexes are responsible for adhesion to extracellular matrix components including fibrinogen, fibronectin, fibronectin, vitronectin, thrombospondin and von Willebrand factor.
Applications Reported: The 2C9.G3 antibody has been reported for use in flow cytometric analysis. 2C9.G3 has also been reported in blocking of ligand binding and some adhesive processes.
Applications Tested: The 2C9.G3 antibody has been tested by flow cytometric analysis of mouse splenocytes and bone marrow cells. This can be used at less than or equal to 0.5 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Storage and handling: Use in a sterile environment.
Filtration: 0.2 µm post-manufacturing filtered.
Purity: Greater than 90%, as determined by SDS-PAGE.
Endotoxin Level: Less than 0.001 ng/µg antibody, as determined by LAL assay.
Aggregation: Less than 10%, as determined by HPLC.
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.
