Vasodilator-stimulated phosphoprotein, VASP.
Vasodilator-stimulated phosphoprotein (VASP) belongs to the Ena-VASP protein family. VASP is linked with filamentous actin formation and likely plays a widespread role in cell adhesion and motility. In addition, VASP may be involved in the intracellular signaling pathways which regulate integrin-extracellular matrix interactions.
VASP Human Recombinant fused with a 20 amino acid His tag at N-terminus produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 363 amino acids (1-343 a.a.) and having a molecular mass of 37.5kDa (Molecular weight on SDS-PAGE will appear higher).
The VASP is purified by proprietary chromatographic techniques.
The VASP solution (0.5 mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 5mM DTT, 10% glycerol, 200mM NaCl and 0.1mM PMSF.
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
