Monoclonal Anti-Vitronectin antibody produced in mouse

Monoclonal Anti-Vitronectin (mouse IgM isotype) is derived from the VIT-2 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with purified human plasma vitronectin. Vitronectin is also referred as serum-spreading factor, S-protein of complement or epibolin. This monomeric acidic protein is one of the major multifunctional cell-adhesive glycoproteins in mammalian plasma and serum. This protein is usually seen as a mixture of 75 kDa and 65 kDa polypeptides. Human plasma and serum contain 0.1-0.4 mg/ml of vitronectin which is synthesized in the liver. It is also present in amniotic fluid and urine.

human plasma vitronectin

Monoclonal Anti-Vitronectin antibody produced in mouse has been used in:

• immunocytochemisry
• western blotting
• immunoprecipitation
• immunofluorescence
• enzyme-linked immunosorbent assay (ELISA)

By immunoblotting, the product shows no cross-reactivity with fibronectin, laminin, merosin, collagen type IV or chondroitin sulfate types A, B and C.

Vitronectin binds to heparin, collagen, streptococci and variety of cultured cells. It also acts as an inhibitor of the complement cascade by binding to the C5b-9 complex. Vitronectin protects thrombin from inactivation by antithrombin III in the presence of heparin, binds and stabilizes the activity of plasminogen activator inhibitor and mediates many other physiological functions.
