| Purity | Greater than 90.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. | Source | Sf9, Insect Cells. |
| Phycical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. | Shipping Condition | Shipped at Room temp. |
| Synonyms | VEGF-C152; Vascular endothelial growth factor C 152; VRP; Flt4 ligand; Flt4-L. | ||
| Solubility | It is recommended to reconstitute the lyophilized Vascular Endothelial Growth Factor C 152 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. | ||
| Stability | Lyophilized Vascular Endothelial Growth Factor-C152 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C . Upon reconstitution VEGF-C 152 should be stored at 4°C between 2-7 days and for future use below -18°C .Please prevent freeze-thaw cycles. | ||
| Biological Activity | Measured by its ability to stimulate phosphorylation of the VEGFR-3/FLT-4 receptor in porcine aortic endothelial cells (PAE/FLT -4 cells). The ED50 for this effect is typically 150-300 ng/ml, corresponding to a specific activity of 3.3-6.6KUnits/mg. | ||
| Formulation | The protein was lyophilized from a concentrated (1mg/ml) solution with BSA. | ||
VEGF-C152S is a point mutant generated by the replacement of the second conserved Cys residue of the recombinant processed VEGF-C by a Ser residue. VEGF-C 152S is analog to the human VEGF-C 156S mutant and only active toward VEGFR-3/FLT-4 but, unlike wild type VEGF-C, is unable to bind to and to activate signaling through VEGFR-2/KDR. VEGF-C152S was inactive in the vascular permeability assay and did not increase migration of the capillary endothelial cells, indicating that these VEGF-like effects of VEGF-C require VEGFR-2 binding. VEGF-C, also known as Vascular Endothelial Growth Factor Related Protein (VRP), is a recently discovered VEGF growth factor family member that is most closely related to VEGF-D. The rat VEGF-C cDNA encodes a pre-pro-protein of 416 amino acids residues. It is almost identical to the mouse VEGF-C protein. Similar to VEGF-D, VEGF-C has a VEGF homology domain spanning the middle third of the precursor molecule and long N- and C-terminal extensions. In adults, VEGF-C is highly expressed in heart, placenta, ovary and small intestine. Recombinant rat VEGF-C, lacking the N- and C-terminal extensions and containing only the middle VEGF homology domain, forms primarily non-covalently linked dimers. This protein is a ligand for both VEGFR-2/KDR and VEGFR-3/FLT -4. Since VEGFR-3 is strongly expressed in lymphatic endothelial cells, it has been postulated that VEGF-C is involved in the regulation of the growth and/or differentiation of lymphatic endothelium. Although recombinant rat VEGF-C is also a mitogen for vascular endothelial cells, it is much less potent than VEGF-A.
