General description

Product Source: E. coli

Vascular endothelial growth factor (VEGF or VEGFA) is a potent mediator of both angiogenesis and vasculogenesis in the fetus and adult. Humans express alternately spliced isoforms of 121, 145, 165, 183, 189, and 206 amino acids (aa) in length. VEGF165 appears to be the most abundant and potent isoform, followed by VEGF121 and VEGF189. VEGF is a potent growth and angiogenic cytokine. It stimulates proliferation and survival of endothelial 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 human VEGF is a 38.2 kDa disulfide-linked homodimeric protein consisting of two 165 amino acid polypeptide chains.
