Vitronectin, also known VTN, is a member of the pexin family. It is a cell adhesion and spreading factor foundin serum and tissues. This protein interacts with glycosaminoglycans and proteoglycans and is recognized by certain members of the integrin family and serves as a cell-to-substrate adhesion molecule. It also contains endogenous cleavage sites such as elastase, thrombin and plasmin. This protein binds multiple ligands, including the soluble vitronectin receptor which affects multi-function. Therefore, it is involved in hemostasis, cell migration, as well as tumor malignancy. Recombinant protein corresponding to aa20-478 from human Vitronectin, fused to His-Tag at C-terminal expressed in Baculovirus. Swiss/Uniprot: P04004 Molecular Weight: ~53.3kD (468aa) Biological Activity: Measured by the ability of the immobilized protein to support the adhesion of B16-F10 mouse melanoma cells. When cells are added to VTN coated plates 5ug/ml. This effect is more to 50%.
