Vitronectin is a plasma glycoprotein that circulates in the blood. Vitronectin is circulating as a mixture of both 75 kDa and 65 kDa forms. Vitronectin is a major cell adhesive glycoprotein and is a common component of extracellular matrix and plasma. It competes effectively with other plasma proteins and is often involved in cell attachment, regulation of blood coagulation and immune responses. It has similar tissue distribution to fibronectin and also its integrin receptor recognises fibronectin (2).
Human vitronectin purified from plasma by heparin-affinity chromatography
CSI 003-08 is highly specific for vitronectin. There is no evidence for cross-reactivity with other connective tissue proteins (fibronectin, elastin, collagen, laminin).
CSI 003-08 cross-reacts with vitronectin from dog, to a lesser extent with cat and sheep.
Epitope is located within a cyanogens bromide cleavage fragment comprising aa 1-310
CSI 003-08 binds nearly as well to native vitronectin as to denatured. It can be used to quantitate vitronectin in human plasma or serum in a sandwich ELISA with antibody CSI 003-02. CSI 003-08 inhibits the binding of PAI-1 to vitronectin. CSI 003-08 also binds to vitronectin in ELISA when vitronectin is coated directly onto the microtiter well.
