ProSpec-VEGF Mouse, Yeast

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

Vascular endothelial growth factor is an important signaling protein involved in both angiogenesis and vasculogenesis.VEGF activity has been mostly studied on cells of the vascular endothelium, although it does have effects on a number of other cell types .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 VEGF is linked to POEMS syndrome, also known as Crow-Fukase syndrome. Mutations in VEGF have been associated with proliferative and nonproliferative diabetic retinopathy.

Vascular Endothelial Growth Factor Mouse Recombinant produced in yeast is a disulfide-linked homodimer consisting of 2×165 amino acid polypeptide chains, having a molecular mass of approximately 40.0kDa each.
VEGF is purified by proprietary chromatographic techniques.

Saccharomyces cerevisiae

Sterile Filtered White lyophilized powder.

Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH 7.4.

It is recommended to reconstitute the lyophilized Vascular Endothelial Growth Factor in sterile 18MΩ-cm H₂O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Lyophilized VEGF although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Vascular Endothelial Growth Factor should be stored at 4°C between 2-7 days and for future use below -18°C.
Please prevent freeze-thaw cycles.

Greater than 97.0% as determined by:
Analysis by RP-HPLC.
Analysis by -PAGE.
