|Detection of Recombinant Rat and Mouse VEGF by Western Blot. Western blot shows 25 ng of Recombinant Rat VEGF 164 (Catalog # 564-RV), Recombinant Human VEGF 165 (Catalog # 293-VE) and Recombinant Mouse VEGF 164 (Catalog # 493-MV). PVDF Membrane was probed with 0.1 µg/mL of Goat Anti-Rat VEGF 164 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF564) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for VEGF at approximately 20-25 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3.|
|VEGF164 in Rat Kidney. VEGF164 was detected in perfusion fixed frozen sections of rat kidney using 15 µg/mL Goat Anti-Rat VEGF164 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF564) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

|Cell Proliferation Induced by VEGF164 and Neutralization by Rat VEGF Antibody. Recombinant Rat VEGF164 (Catalog # 564-RV) stimulates proliferation in HUVEC human umbilical vein endothelial cells in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Rat VEGF164 (20 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Rat VEGF 164 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF564). The ND50 is typically 0.2-0.6 µg/mL.|
Vascular endothelial growth factor (VEGF or VEGF-A), also known as vascular permeability factor (VPF), is a potent mediator of both angiogenesis and vasculogenesis in the fetus and adult. It is a member of the PDGF family that is characterized by a cysteine-knot structure formed by eight conserved cysteine residues. Alternately spliced isoforms of 121, 145, 165, 183, 189, and 206 amino acids (aa) have been identified in humans, with 120, 164, and 188 aa isoforms found in rat and mouse. Isoforms other than VEGF120 and VEGF121 contain basic heparin-binding regions and are not freely diffusible. Rat VEGF164 shares 97% aa sequence identity with corresponding regions of mouse, 88% with human and bovine, 89% with porcine and canine, and 90% with feline and equine VEGF, respectively. VEGF binds the type I transmembrane receptor tyrosine kinases VEGF R1 (also called Flt-1) and VEGF R2 (Flk-1/KDR) on endothelial cells. Although affinity is highest for binding to VEGF R1, VEGF R2 appears to be the primary mediator of VEGF angiogenic activity. Human VEGF165 binds the semaphorin receptor, neuropilin-1 and promotes complex formation with VEGF R2. VEGF is required during embryogenesis to regulate the proliferation, migration, and survival of endothelial cells. In adults, VEGF functions mainly in wound healing and the female reproductive cycle. Pathologically, it is involved in tumor angiogenesis and vascular leakage. Circulating VEGF levels correlate with disease activity in autoimmune diseases such as rheumatoid arthritis, multiple sclerosis and systemic lupus erythematosus. VEGF is induced by hypoxia and cytokines such as IL-1, IL-6, IL-8, oncostatin M, and TNF-alpha.
