By utilizing an easy-to-use, xeno-free, defined, recombinant human ECM, laboratories can achieve more consistent results without the variability associated with undefined serum-based reagents.
Technical Specifications and Structural Consi VTN Gene - GeneCards | VTNC Protein | VTNC Antibody derations
From a structural perspective, the VTN (Vitronectin) gene encodes a protein that is synthesized in the liver and secreted into the bloodstream. It is well-known that the vitronectin peptide, such as the [351–359] h-Vitronectin sequence, can be used to functionalize surfaces like 3D-printed PEEK disks to improve biocompatibility.
When sourcing these materials, it is important to note the specific characteristics of the peptide. For instance, the Vitronectin (367-378) fragment is frequently studied for its role in cell growth and its interaction with integrins. Whether you are working with a VTN/Vitronectin His Tag Protein or a specific amino acid fragment, the purity and the specific sequence design are paramount to the success of the experiment.
Observations on Laboratory Usage
In my own experience with these compounds, the transition toward a synthetic, xeno-free alternative has been a game-changer. By using a fragment that mimics the native protein, we eliminate the risks associated with xenogenic contaminants. It is fascinating to see how a simple sequence—a fr Recombinant Vitronectin, Solution, 0.5 mg/ml #5121 agment or bioactive sequence derived from the vitronectin protein—can replicate the complex adhesive properties of the native molecule.
Furthermore, because vitronectin is a member of the pexin family, its structural stability is generally high, making it an excellent candidate for coating plates or flasks. Whether you are investigating the role of VTN as a plasma glycoprotein or attempting to induce specific cellular pathways, the precision offered by these engineered peptides is unmatched.
