Vascular Endothelial Growth Factor (VEGF) ELISA Kit

  • Created on the 7 February, 2017.

BACKGROUND

Vascular endothelial growth factor (VEGF) is a cytokine which can stimulate many cellular responses by binding to tyrosine kinase receptors (i.e. VEGFRs) that are present on the cell surface, this results in the formation of dimers which are can then be activated by transphosphorylation. VEGF is a vital signalling protein that is found to be involved in both angiogenesis and vasculogenesis, as its name suggests VEGF activity is largely restricted to vascular endothelium cells, however, it does have some limited effect on other cells such as macrophages and monocytes.

The VEGF receptors consists of an extracellular portion that is made up of 7 immunoglobulin-like domains, a single transmembrane spanning region and an intracellular portion which consists of a split tyrosine-kinase domain. In addition to binding to VEGFRs, there is evidence that VEGF is able to bind to receptor complexes consisting of both VEGFRs and neuropilins. This receptor complex is found result in an increase in VEGF signalling activity in blood vessels (endothelial cells). There are essentially three main subtypes of VEGFR which can be numbered 1, 2 and 3. There is also a membrane-bound (mbVEGFR) or soluble (sVEGFR).

INTENDED USE

Human VEGF ELISA kit is a reliable quantitative procedure for measuring vascular endothelial growth factor (VEGF) in human serum, plasma (heparin, citrate, EDTA) and cell culture supernatant. This assay has a minimum sensitivity detection limit of < 1.0 pg/ml.

SENSITIVITY

The minimum sensitivity detection limit of vascular endothelial growth factor (VEGF) using this VEGF ELISA kit was approximately < 1.0 pg/ml. The dynamic assay range for this kit is 31.2 – 2000.0 pg/ml (serum and plasma) and 15.6 – 1000.0 pg/ml (cell culture supernatant).

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA kit performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA kits from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
