Recombinant Human Vitronectin Protein, CF Summary

Purity
>90%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie® Blue Staining.
Endotoxin Level
<0.10 EU per 1 μg of the protein by the LAL method.
Activity
Measured by the ability of the immobilized protein to support the adhesion of B16‑F1 mouse melanoma cells. When 5 x 104 cells/well are added to Vitronectin coated plates (5 µg/mL with 100 µL/well), approximately >55% will adhere after 30 minutes at 37 °C.
Optimal concentration depends on cell type as well as the application or research objectives.

Product Datasheets

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: Vitronectin

Vitronectin is a large glycoprotein found in blood and the extracellular matrix (ECM). The gene for Vitronectin encodes a 19 amino acid (aa) signal peptide and a 459 aa protein. The amino terminal 130 aa residues of Vitronectin contain multiple binding sites for a variety of structures. Included is a site for binding to plasminogen activator inhibitor-1 (PAI‑1) and urokinase receptor, an (RGD) sequence that binds alpha v beta 3, alpha v beta 5, alpha v beta 1, alpha IIb beta 3, alpha v beta 6, and alpha v beta 8 integrins, a stretch of acidic amino acids that includes two sulfated tyrosine residues that bind thrombin-anti-thrombin III complexes, and a collagen binding site. The major part of the Vitronectin molecule
(aa 132-459) contains six hemopexin-like repeats. The carboxyl-terminal end of Vitronectin also has multiple sites and functions. It contains a stretch of basic amino acids that binds the acidic amino acids of the amino-terminal region, thereby stabilizing Vitronectin’s three dimensional structure. The carboxyl-terminal end also contains a plasminogen binding site, a heparin binding site that binds complement factor C7, C8 or C9, a glycosaminoglycan binding site, and a second PAI-1 binding site (aa 348-370). Vitronectin also contains an endogenous cleavage site, plus cleavage sites for elastase, thrombin and plasmin. Vitronectin has also been shown to bind IGF-2 and TGF-beta. The apparent molecular weight of human Vitronectin is 75 kDa, with ~30% of its molecular mass being attributed to glycosylation at 3 different sites. In blood and plasma, Vitronectin is found predominantly as a single chain monomer. It can also be found as a dimer after endogenous cleavage. The dimer is composed of a 65 kDa and 10 kDa component held together by a disulfide bond. Binding of thrombin-anti-thrombin II complex or complement leads to an unfolding of Vitronectin. Unfolding of Vitronectin generates disulfide-linked multimers that are found in platelet secretions and extracellular matrix. Vitronectin is produced at high levels by the liver and many tumors. As might be expected by its structure, Vitronectin is involved in a number of biological activities including cell adhesion, cell spreading and migration, cell proliferation, extracellular anchoring, fibrinolysis, hemostasis, and complement mediated immune defense.
