| Source | Human VEGF-165, amino acids Ala27-Arg191 (Accession# AAM03108) was expressed in 293E cells. |
|---|---|
| Molecular Mass | The 165 amino acid recombinant protein has a predicted molecular mass of approximately 19 kD. The DTT-reduced protein migrates at approximately 20-28 kD and non-reduced protein migrates at 50 kD by SDS-PAGE. The N-terminal amino acid is Alanine. |
| N-terminalSequence Analysis | Ala-Pro-Met-Ala-Glu-Gly-Gly-Gly-Gln-Asn |
| Purity | ≥ 95%, as determined by Coomassie stained SDS-PAGE |
| Formulation | 0.1 µm filtered protein solution is in 5 mM citric acid, 5 mM Na2HPO4, 0.15 M NaCl pH 4.0. |
| Endotoxin Level | Less than or equal to 0.1 EU per μg protein as determined by the LAL method |
| Residual Host Cell Protein Content | ≤ 0.500 ng/μg by ELISA |
| Concentration | 500 µg/mL |
| Storage & Handling | Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% endotoxin-free BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week or stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles. |

| Function | VEGFA is a key player in vasculogenesis, the formation of blood vessels from progenitor cells, as well as angiogenesis. The expression of the VEGFA gene is upregulated via hypoxia, estrogen, and NF-κB pathways. In addition, VEGFA is upregulated by PDGF-BB, P1GF, TGFβ1, IGF1, FGFs, HGF, TNFα, and IL-1. VEGFA induces proliferation and cell migration in endothelial cells, and plays important roles during wound healing. Also, VEGFA regulates haematopoietic stem cell survival. VEGFA interacts with vascular endothelial cells and monocytes/macrophages, which express VEGFR1. This interaction induces proliferation of endothelial cells and stimulates migration of monocytes/macrophages. VEGFR2 is expressed in endothelial cells and VEGFR2-signaling is essential for the development of vascular systems in the embryo. |
