Vascular endothelial growth factor-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 the mRNA for VEGF-A results in several isoforms of the protein being produced. 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 Murine VEGF is a double, non-glycosylated, polypeptide chain containing 165 amino acids and having a molecular mass of 39kD.

Sequence:
The sequence of the first five N-terminal amino acids was determined and was found to be Met-Ala-Pro-Thr-Thr.

Biological Activity:
Determined by the dose-dependent stimulation of the proliferation of human umbilical vein endothelial cells (HUVEC) using a concentration range of 1.0-6.0ng/ml.

Storage and Stability:
Lyophilized powder may be stored at -20C. Reconstitute to nominal volume by adding sterile dH2O, 0.1% BSA or HSA. Aliquot and store at -20C. Reconstituted product is stable for 12 months at -20C. For maximum recovery of product, centrifuge the original vial prior to removing the cap.

Molecular Weight:
39.036kD
