Protein Family: CAM Ligands, Cytokines
Pathway and Disease: Cell Growth and Death, Signal Transduction
Alternate Names: Vascular endothelial growth factor a, VEFG-a, vascular permeablility factor, VPF, VEFGA, VEGFDescription:
Vascular endothelial growth factor-A (VEGF-A) was originally isolated from tumor cells and referred to as Tumor Angiogenesis Factor or Vascular Permeability Factor. Although expressed at high levels in certain tumor-derived cells it is produced by a wide variety of cell types. In addition to stimulating vascular growth and vascular permeability, it may play a role in stimulating vasolidation via nitric oxide-dependent pathways. Alternative splicing of VEGF-A mRNA results in several isoforms of the protein. Rat and bovine VEGF are one amino acid shorter than the human factor, and the bovine and human sequences show a homology of 95 percent. In contrast to other factors mitogenic for endothelial cells such as FGF-1 , FGF-2 and PDGF, VEGF is synthesized as a precursor containing a typical hydrophobic secretory signal sequence of 26 amino acids. Glycosylation is not required for efficient secretion of VEGF. Recombinant Human VEGF-121 produced in E. coli is a double, non-glycosylated, polypeptide chain containing 121 amino acids with a MW of 28,423 Da.
Source: E. coli. Endotoxin level as measured by LAL is <0.01ng/ug or <0.1EU/ug.
Applications: E, WB
Application Notes:
The biological activity is determined by the dose-dependent stimulation of the proliferation of human umbilical vein endothelial cells (HUVEC) using a concentration range of 0.1-0.4 ng/ml.
Accession No.: P15692
MW: 28423 Da

Purity:
Purity > 95% as determined by RP-HPLC and reducing and non-reducing SDS-PAGE. Protein Content determined by UV spectroscopy at 280 nm and analysis by RP-HPLC calibrated against a known standard. Quantitation on SDS-PAGE against a known standard.
Format:
Each vial contains 10 ug of lyophilized protein. Reconstitute with 0.1 ml sterile deionized water for a final concentration of 0.1 mg/ml.
Storage: Store at -20°C. Product is guaranteed one year from the date of shipment. Following reconstitution, store at -20°C. We recommend to add a carrier protein (0.1% HSA or BSA) for long term storage.
