Synonyms:
Vascular endothelial growth factor A, VEGF-A, Vascular permeability factor, VPF, VEGF, MGC70609.

Introduction:
Vascular endothelial growth factor is an important signaling protein involved in both vasculogenesis and angiogenesis. As its name implies, VEGF activity has been mostly studied on cells of the vascular endothelium, although it does have effects on a number of other cell types (e.g. stimulation monocyte/macrophage migration, neurons, cancer cells, kidney epithelial cells ). VEGF mediates increased vascular permeability, induces angiogenesis, vasculogenesis and endothelial cell growth, promotes cell migration, and inhibits apoptosis. In vitro, VEGF has been shown to stimulate endothelial cell mitogenesis and cell migration. VEGF is also a vasodilator and increases microvascular permeability and was originally referred to as vascular permeability factor.
Elevated levels of this protein is linked to POEMS syndrome, also known as Crow-Fukase syndrome. Mutations in this gene have been associated with proliferative and nonproliferative diabetic retinopathy.

Description:
Vascular Endothelial Growth Factor Human Recombinant produced in Yeast is a double, glycosylated, polypeptide chain containing 165 amino acids and having a molecular mass of 42 kDa.

Source:
Pichia Pastoris

Physical Appearance:
Sterile Filtered colorless liquid formulation.

Formulation:
The protein contains 20mM Phosphate- Buffered Saline, pH 7.4.

Stability:
Vascular Endothelial Growth Factor Human although stable at 15°C for 2 weeks, should be stored desiccated below -18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.

Purity:
Greater than 90.0% as determined by SDS-PAGE.

Biological Activity:
Determined by its ability to stimulate ³H-Thymidine incorporation in human umblical vein endothelial cells, the ED₅₀ for this effect was found to be 2-6 ng/ml. The specific Activity was found to be 1 x 10⁵units/mg.
