Vegfc-454R |
Description : |
Rat 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. 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. rRa 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 rRa VEGF-C is also a mitogen for vascular endothelial cells, it is much less potent than VEGF-A. rRa VEGF-C contains 129 amino acids residues. As a result of glycosylation VEGF-C migrates as an 18-24 kDa protein in SDS-PAGE under reducing conditions. |
Source : |
Insect cells. |
Molecular Weight : |
18-24 kDa. |
Endotoxin Level : |
< 0.1 ng per µg of rRa VEGF-C (1EU/µg). |
Purity : |
> 90% as determined by SDS-PAGE, RP-HPLC and AEX-FPLC. |
Biological Activity : |
Measured by its ability to stimulate phosphorylation of the VEGFR-3/FLT-4 receptor in porcine aortic endothelial cells. The ED50for this effect is typically 200-300 ng/ml. |
Formulation : |
Lyophilized protein from a concentrated solution with BSA. |
Reconstitution : |
Please Note: Always centrifuge product before opening the vial. The lyophilized protein should be reconstituted in water to a concentration of 0.1-1.0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use. |
Storage/Stability : |
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted VEGF-C should be used immediately or stored long-term in undiluted working aliquots at –20°C. For long-term storage, it is recommended to add a carrier protein (0.1% HSA or BSA). Please avoid repeated freeze / thaw cycles. |
