Application CommentsDoes not cross-react with fibronectin, fibrinogen, or von Willebrand factor. This antibody will inhibit TSP-collagen interactions. Its binding to TSP is unaffected by glycosaminoglycans (e.g., hyaluronic acid, chrondroitin sulfate and heparin). EDTA (i.e., low concentrations of Ca2+) enhances the binding capacity of Clone A6.1 to TSP. This antibody has been reported to work in immunofluorescence, flow cytometry, and electron microscopy. Antibody should be titrated for optimal results in individual systems.

DescriptionPurified mouse monoclonal antibody generated by immunizing BALB/c mice with the specified immunogen and fusing splenocytes with SP2/Ag14 mouse myeloma cells. Recognizes the ~450 kDa (non-reduced) or the ~180 kDa (reduced) thrombospondin (TSP) protein.
BackgroundThrombospondin (TSP) is a ~450 kDa glycoprotein synthesized by platelets, as well as by monocytes, macrophages, fibroblasts and endothelial cells. Although TSP is the major α-granule protein of human platelets, the concentration of the protein in circulating plasma is quite low. Upon stimulation of platelets, the TSP is expressed on the cell surface where it plays a role in platelet aggregation and other cell-cell interactions. Studies show that the platelet-monocyte association has been demonstrated to be mediated by the interaction of TSP on the platelet surface with a monocyte TSP receptor. The receptor has been identified immunologically as glycoprotein IV, also known as GPIIIb and CD36, a ~90 kDa membrane glycoprotein expressed on platelets, endothelial cells, erythrocytes, monocytes, and some human tumor cells lines but not on lymphocytes or granulocytes. Recent studies have shown that TSP-1 is a naturally occurring inhibitor of angiogenesis whose actions are mediated by CD36, found on microvascular endothelial cells.
