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 VEGF is a 38.5kD disulfide-linked homodimeric protein consisting of two 165aa polypeptide chains. Source: Recombinant protein corresponding to rat VEGF165, expressed in E.coli. Biological Activity: Determined by the dose-dependent stimulation of the proliferation of Human umbilical vein endothelial cells (HUVEC). The expected ED50 is 4-8ng/ml. Endotoxin: <0.1ng/ug (1EU/ug) AA Sequence: MAPTTEGEQK AHEVVKFMDV YQRSYCRPIE TLVDIFQEYP DEIEYIFKPS CVPLMRCAGC CNDEALECVP TSESNVTMQI MRIKPHQSQH IGEMSFLQHS RCECRPKKDR TKPEKHCEPC SERRKHLFVQ DPQTCKCSCK NTDSRCKARQ LELNERTCRC DKPRR Storage and Stability: May be stored at 4 degrees C for short-term only.
