VEGF (vascular endothelial growth factor) is a heparin-binding cytokine and member of the PDGF/VEGF growth factor family, which acts as a vasodilator, regulator of vasculogenesis, and is a potent stimulator of angiogenesis of both normal and cancerous cells.
All VEGF family members act through binding to the tyrosine kinase receptors VEGFR-1 (Flt-1) and VEGFR-2 (KDR/CD309), and the functional forms of VEGF, which exist as disulphide-linked homodimers, are classified according to the number of amino acid residues within a constitutive polypeptide chain e.g VEGF165.
Purified recombinant protein - lyophilised
Reconstitute with 100ul distilled water Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Bio-Rad recommend that the vial is gently mixed after reconstitution.
Purified recombinant VEGF expressed in E.coli
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.
