| Background Information | VEGF (Vascular endothelial growth factor, VEGFA, VEGF-A), a dimeric ligand, is among the most potent angiogenic mitogens. VEGF is secreted by tumor cells and other cells exposed to hypoxia. VEGF is a highly specific mitogen for vascular endothelial cells. Seven VEGF isoforms (a, b, c, d, e, f, g) are generated as a result of alternative splicing from a single VEGF gene. The most commonly studied isoforms are VEGF121, VEGF165, and VEGF189 (f, d and b, respectively) All seven isoforms differ in their molecular mass and in biological properties such as their ability to bind to cell-surface heparan-sulfate proteoglycans. The expression of VEGF is potentiated and is secreted by tumor cells in response to hypoxia, by activated oncogenes, and by a variety of cytokines. VEGF induces angiogenesis as well as permeabilization of blood vessels, and plays a central role in the regulation of vasculogenesis. VEGF expression correlates to the degree of tumor vascularization and with increased metastatic risk. Additionally, VEGF induces endothelial cell proliferation, promotes cell migration, and inhibits apoptosis. Consequently, inhibition of VEGF signaling abrogates the development of a wide variety of tumors. |

|---|---|
| Application | Anti-VEGF Antibody detects level of VEGF & has been published & validated for use in WB, IH(P), ELISA. |
| Key Applications |
|
| Application Notes | Immunohistochemisty (paraffin): VEGF staining in mouse placenta, tissue was pretreated with citrate buffer, pH 6.0. A previous lot of antibody was diluted to 1:100, using IHC-Select® detection with HRP-DAB. Neutralization: To yield one-half maximal inhibition [ND50] of the biological activity of mouse VEGF (50.0 ng/mL), a concentration of 1.0-2.0 µg/mL of a previous lot of this antibody was required. ELISA: A concentration of at least 0.5 µg/mL (100 μL/well) is required to detect 0.2-0.4 ng/well of recombinant mouse VEGF using a previous lot of this antibody. Optimal working dilutions must be determined by the end user. |

| Entrez Gene Number |
|
| Entrez Gene Summary | This gene is a member of the PDGF/VEGF growth factor family and encodes a protein that is often found as a disulfide linked homodimer. This protein is a glycosylated mitogen that specifically acts on endothelial cells and has various effects, including mediating increased vascular permeability, inducing angiogenesis, vasculogenesis and endothelial cell growth, promoting cell migration, and inhibiting apoptosis. Elevated levels of this protein is linked to POEMS syndrome, also known as Crow-Fukase syndrome. Mutations in this gene have been associated with proliferative and nonproliferative diabetic retinopathy. Alternatively spliced transcript variants, encoding either freely secreted or cell-associated isoforms, have been characterized. There is also evidence for the use of non-AUG (CUG) translation initiation sites upstream of, and in-frame with the first AUG,leading to additional isoforms. [provided by RefSeq]. |

| UniProt Summary | FUNCTION: Growth factor active in angiogenesis, vasculogenesis and endothelial cell growth. Induces endothelial cell proliferation, promotes cell migration, inhibits apoptosis, and induces permeabilization of blood vessels. Binds to the VEGFR1/Flt-1 and VEGFR2/Kdr receptors, heparan sulfate and heparin. Neuropilin-1 binds isoforms VEGF-165 and VEGF-145. SUBUNIT: Homodimer; disulfide-linked. Also found as heterodimer with PlGF (By similarity). SUBCELLULAR LOCATION: Secreted. Note=VEGF121 is acidic and freely secreted. VEGF165 is more basic, has heparin-binding properties and, although a signicant proportion remains cell-associated, most is freely secreted. VEGF189 is very basic, it is cell-associated after secretion and is bound avidly by heparin and the extracellular matrix, although it may be released as a soluble form by heparin, heparinase or plasmin. ALTERNATIVE PRODUCTS: 10 named isoforms [FASTA] produced by alternative splicing. |

| Storage and Shipping Information | |
|---|---|
| Storage Conditions | Reconstituted antibody, at a concentration of ≥ 0.2 mg/mL, is stable for at least six weeks at 2-8ºC. Aliquots stored at -20ºC are stable for at least one year from date of receipt. Handling Recommendations: Upon first thaw, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. |
