Description

VEGF (also known as VEGF-A) is a signaling protein with strong vascular permeability activity that stimulates the formation of new blood vessels during the processes of vasculogenesis and angiogenesis. It is a member of the vascular endothelial growth factor family, which in mammals is comprised of VEGF-A, VEGF-B, VEGF-C, VEGF-D, and PlGF (placental growth factor). There are multiple isoforms of VEGF that result from alternative splicing of mRNA. VEGF binds and activates two tyrosine kinase receptors, VEGFR1 (Flt-1) and VEGFR2 (KDR/Flk-1), through which VEGF exerts its mitogenic effects. VEGF is highly expressed in solid tumors of breast, lung, renal, colorectal, and hepatic origin. Additionally, it significantly contributes to ascites tumor formation. Beyond cancer, VEGF has also been associated with multiple pathogenic conditions including rheumatoid arthritis, age-related macular degeneration, Crow-Fukase syndrome, sclerosis and Alzheimer’s disease.

Application

ELISA Detection - Quality tested

Recommended Usage

Each lot of this antibody is quality control tested by ELISA assay. For ELISA Detection applications, a concentration range of 0.1 - 1 µg/mL is recommended. To obtain a linear standard curve, serial dilutions of VEGF recombinant protein ranging from 23.4 to 1,500 pg/mL is recommended for each ELISA plate. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

The biotinylated Poly5225 antibody is useful as the detection antibody in a sandwich ELISA assay, when used in conjunction with purified A15136H antibody (Cat. No. 537002) as the detection antibody and Recombinant Human VEGF (ELISA Std.) (Cat. No. 560309)

Function
VEGFA is a key player in vasculogenesis, the formation of blood vessels from progenitor cells, as well as angiogenesis. The expression of the VEGFA gene is upregulated via hypoxia, estrogen, and NF-κB pathways. In addition VEGF is upregulated by PDGF-BB, P1GF, TGFβ1, IGF1, FGFs, HGF, TNFα, and IL-1. VEGFA induces proliferation and cell migration in endothelial cells and plays important roles during wound healing. Also, VEGF regulates hematopoietic stem cell survival.
Interaction
VEGFA interacts with vascular endothelial cells and monocytes/macrophages, which express VEGFR1. This interaction induces proliferation of endothelial cells and stimulates migration of monocytes/macrophages
Ligand Receptor
Vascular endothelial growth factor (VEGF)-A binds and activates two tyrosine kinase receptors, VEGFR1 (Flt-1) and VEGFR2 (KDR/Flk-1)
