Vitronectin is a plasma glycoprotein that circulates in the blood. Vitronectin is circulating as a mi, Xenopus/Amphibian,ture of both 75 kDa and 65 kDa forms. Vitronectin is a major cell adhesive glycoprotein and is a common component of e, Xenopus/Amphibian,tracellular matri, Xenopus/Amphibian, 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. This antibody is highly specific for vitronectin. There is no evidence for cross-reactivity with other connective tissue proteins (fibronectin, elastin, collagen, laminin This antibody reacts with vitronectin from cat, dog, goat, cow and to a lesser e, Xenopus/Amphibian,tent with horse.
