Description

VEGF is a potent growth and angiogenic cytokine. It stimulates proliferation and survival of endothellial cells, and promotes angiogenesis and vascular permeability. Expressed in vascularized tissues, VEGF plays a prominent role in normal and pathological angiogenesis. Substantial evidence implicates VEGF in the induction of tumor metastasis and intra-ocular neovascular syndromes. VEGF signals through the three receptors; fms-like tyrosine kinase(flt-1), KDR gene product (the murine homolog of KDR is the flk-1 gene product) and the flt4 gene product. Recombinant Rat VEGF165 is a 38.5 kDa, disulfide-linked homodimeric protein consisting of two 165 amino acid polypeptide chains.

Biological Activity

Determined by the dose-dependent stimulation of the proliferation of human umbilical vein endothelial cells (HUVEC). The expected ED50 is 4.0–8.0 ng/ml.

Endotoxin

Endotoxin level is <0.1 ng/μg of protein (<1EU/μg).

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1–1.0 mg/ml. Do not vortex. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at –20°C to –80°C.

Storage/Expiration

 –20°C
