N-VEGF. Participates in the induction of key genes involved in the response to hypoxia and in the induction of angiogenesis such as HIF1A (PubMed:35455969). Involved in protecting cells from hypoxia-mediated cell death (PubMed:35455969). VEGFA. 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 FLT1/VEGFR1 and KDR/VEGFR2 receptors, heparan sulfate and heparin. Binds to the NRP1/neuropilin-1 receptor. Binding to NRP1 receptor initiates a signaling pathway needed for motor neuron axon guidance and cell body migration, including for the caudal migration of facial motor neurons from rhombomere 4 to rhombomere 6 during embryonic development (PubMed:26503042). Also binds the DEAR/FBXW7-AS1 receptor (PubMed:16293765). May play a role in increasing vascular permeability during lactation, when increased transport of molecules from the blood is required for efficient milk protein synthesis (By similarity).

Mouse VEGF ELISA Kit (ab209882) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of VEGF protein in cell culture extracts, cell culture supernatant, and tissue extracts. It uses our proprietary SimpleStep ELISA® technology. Quantitate Mouse VEGF with 0.3 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (Pre-coated 384 well Microplate SimpleStep ELISA® ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
VEGF is a secreted growth factor of PDGF family active in angiogenesis, vasculogenesis and endothelial cell growth both in fetus and adult. Alternative splicing produces isoforms including 120, 164 and 188 amino acid long forms in mouse. VEGF induces endothelial cell proliferation, promotes cell migration, inhibits apoptosis and induces permeabilization of blood vessels. VEGF dimers bind to the FLT1/VEGFR1 and KDR/VEGFR2 receptors, induce their homodimerization and autophosphorylation.

Vascular endothelial growth factor A (VEGFA) also known as VEGF or vascular permeability factor (VPF) is a protein that plays a central role in angiogenesis as well as in the growth of blood vessels. The molecular weight of VEGFA varies depending on the isoform typically ranging from 34 to 42 kDa. VEGFA is expressed in many tissues including fibroblasts macrophages endothelial cells and platelets. Its expression levels can increase in response to stimuli like hypoxia or inflammatory cytokines. VEGFA is an important target in research for therapies related to vascular diseases and cancer.
VEGFA functions by promoting the proliferation and migration of vascular endothelial cells. It operates both as a homodimer and as part of complex signaling cascades interacting with VEGF receptors on cell surfaces to trigger downstream signals for angiogenesis. This includes endothelial cell growth migration and the new blood vessel formation process. VEGFA's activity is important for physiological processes such as wound healing and embryonic development and it also contributes to pathological conditions through its unregulated expression in diseases.
Many processes involve VEGFA including the PI3K/AKT pathway and the MAPK/ERK pathway. These pathways regulate cell survival growth and differentiation. Other proteins like PLGF (placenta growth factor) and VEGFB often accompany VEGFA in these pathways aiding in distinct but overlapping roles. These interactions are transmitted through binding to VEGF receptors such as VEGFR-1 and VEGFR-2 subsequently activating various signaling cascades necessary for cellular and tissue homeostasis.
VEGFA relates to cancer and age-related macular degeneration among others. In cancer overexpression of VEGFA can lead to excessive angiogenesis supplying blood to tumors and facilitating tumor growth. In age-related macular degeneration upregulation of VEGFA contributes to the progression of the disease by promoting the formation of abnormal blood vessels under the retina. Anti-VEGFA therapies such as anti-VEGF antibodies (e.g. bevacizumab) can target these overexpressed pathways. VEGFA interacts with other proteins like HIF-1α which regulates its expression under hypoxia a common condition in tumors.

Interpolated concentrations of native VEGF in Mouse cell culture supernatant samples.
The concentrations of VEGF were measured in duplicates, interpolated from the VEGFA standard curves and corrected for sample dilution. Undiluted samples are as follows: 5 μg/mL LPS-treated P388D1 Day 6 supernatant 7.5%, lung day 5 supernatant 15%, kidney day 5 supernatant 30%, heart day 5 supernatant 30%.
