Vitronectin is a 478 amino acid protein (1-19aa = signal domain) that belongs to a member of the pexin family. Vitronectin is an abundant glycoprotein found in serum and the extracellular matrix. It promotes cell adhesion and spreading, inhibits the membrane-damaging effect of the terminal cytolytic complement pathway, and binds to several serpin serine protease inhibitors. It is a secreted protein and exists in either a single chain form or a clipped, two chain form held together by a disulfide bond.

Vitronectin has been speculated to be involved in hemostasis and tumor malignancy. Recombinant human Vitronectin gene (20-398 aa Fragment) was constructed with codon optimization and expressed in non-fusion protein form in E.coli as inclusion bodies. The final product was refolded using a unique “temperature shift inclusion body refolding” technology and chromatographically purified.

Vitronectin is ideal for coating of surfaces. The optimal concentration for cell attachment and culture may differ for various cell types. Vitronectin has been used at a final coating concentration as low as 50 ng/cm x cm on plasticware. It is provided in user-friendly packaging for use and storage. Vitronectin is sterile filtered and is supplied as a ready to use solution after thawing and concentration adjustment.
