Anti-Vitronectin (human, dog, cat, goat, horse, bovine)

Cat.No. CSI 003-23

Cat. No.
CSI 003-23
Product name
Anti-Vitronectin (human, dog, cat, goat, horse, bovine)

Mouse monoclonal antibody

CSI 003-23 is highly specific for vitronectin. There is no evidence for cross-reactivity with other connective tissue proteins (fibronectin, elastin, collagen, laminin).
CSI 003-23 binds nearly as well to native vitronectin as to denatured. CSI 003-23 is a potent inhibitor of integrin-mediated cell adhesion to vitronectin and a moderate inhibitor of PAI-1 binding.

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).

Application 1


CSI 003-23 also binds to vitronectin in ELISA when vitronectin is coated directly onto the microtiter well. In Western blotting a dilution guideline of 1/50 and 1/200 has proved successful (1,2).
Application 2


CSI 003-23 can be used in Western blotting (1)
