Scientific Data Images for Human/Primate VEGF Antibody

Detection of Human VEGF antibody by Western Blot.

Detection of Human VEGF by Western Blot.

Western blot shows lysates of human lung tissue. PVDF membrane was probed with 2 µg/mL of Recombinant Mouse Anti-Human/Primate VEGF Monoclonal Antibody (Catalog # MAB293R) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for VEGF at approximately 25 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
VEGF antibody in Human Liver by Immunohistochemistry (IHC-P).

VEGF in Human Liver.

VEGF was detected in immersion fixed paraffin-embedded sections of human liver using Recombinant Mouse Anti-Human/Primate VEGF Monoclonal Antibody (Catalog # MAB293R) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in hepatocytes. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.
Cell Proliferation Induced by VEGF165and Neutralization by Human VEGF Antibody.

Cell Proliferation Induced by VEGF165and Neutralization by Human VEGF Antibody.

Recombinant Human VEGF165(Catalog # 293-VE) stimulates proliferation in HUVEC human umbilical vein endothelial cells in a dose-dependent manner (orange line), as measured by Resazurin (Catalog # AR002). Proliferation elicited by Recombinant Human VEGF165(10 ng/mL) is neutralized (green line) by increasing concentrations of Recombinant Mouse Anti-Human/Primate VEGF Monoclonal Antibody (Catalog # MAB293R). The ND50 is typically 10-60 ng/mL.

Background: VEGF

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 the presence of eight conserved cysteine residues and a cystine knot structure. VEGF165 appears to be the most abundant and potent isoform, followed by VEGF121 and VEGF189. Human VEGF165 is an approximately 44 kDa molecular weight homodimer sharing 88% aa sequence identity with corresponding regions of mouse and rat, 96% with porcine, 95% with canine, and 93% with feline, equine and bovine 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 VEGF affinity is highest for binding to VEGF R1, VEGF R2 appears to be the primary mediator of VEGF angiogenic activity. VEGF165 binds the Semaphorin receptor, Neuropilin-1 and promotes complex formation with VEGF R2. VEGF is required during embryogenesis and functions 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 (OSM) and TNF-alpha.
