About This Kit
Kit Overview
The Basic VEGF-A Human ELISA Kit is an enzyme-linked immunosorbent assay for the quantitative detection of human VEGF-A. This assay is designed to detect and quantify the level of human VEGF-A in serum, plasma (EDTA, citrate, and heparin), and cell culture supernatant.
Principle of the assay
The Human VEGF-A solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) follows a unique approach to measure the amount of the target molecule. It utilizes a matched pair of antibodies to capture the target and form a sandwich complex. The first antibody is pre-coated on the microplate wells, where samples, standards, or controls are added and bind to the immobilized antibody. The second antibody, acting as the detector, is then introduced, followed by the addition of a substrate solution that generates a measurable signal upon interaction with the enzyme-antibody-target complex. The intensity of this signal directly correlates to the concentration of the target present in the original specimen.

Target information
VEGF (vascular endothelial growth factor) which is a 45 kDa homodimeric, disulfide-linked glycoprotein involved in angiogenesis which promotes tumor progression and metastasis. VEGF has a variety of effects on vascular endothelium, including the ability to promote endothelial cell viability, mitogenesis, chemotaxis, and vascular permeability. The VEGF family currently includes VEGF-A, VEGF-B, VEGF-C, VEGF-D, VEGF-E, and PIGF. VEGF and its receptor system have been shown to be the fundamental regulators in the cell signaling of angiogenesis. Most tumors have the absolute requirement of angiogenesis, and VEGF has been described as the most potent angiogenic cytokine linked to this process. To date 5 different isoforms of VEGF have been described. These isoforms are generated as the result of alternative splicing from a single VEGF gene. These various isoforms have been shown to bind to two tyrosine-kinase receptors flt-1 (VEGFR-1) and flk-1/KDR (VEGFR-2), which have been found to be expressed almost exclusively on endothelial cells. VEGF and its high-affinity binding receptors, the tyrosine kinases FLK1 and FLT1, are thought to be important for the development of embryonic vasculature. Studies have shown that an alternately spliced form of FLT1 produces a soluble protein, termed sFLT1, which binds vascular endothelial growth factor with high affinity, playing an inhibitory role in angiogenesis. Elevated levels of VEGF is linked to POEMS syndrome (Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal gammopathy, Skin changes) also known as Crow-Fukase syndrome which affects multiple organs in the body.
