Detection of Human VEGFR2/KDR/Flk-1 by ELISA

Detection of Human VEGFR2/KDR/Flk-1 by ELISA

Humoral response in pre-clinical models. Specific IgG antibodies were detected by ELISA using GST-hVEGF as coating antigen (a, b, d and f). The ability of animal sera antibodies to block VEGF/VEGFR2 interaction was determined using a competitive ELISA, where a soluble VEGFR2 competes with diluted serum in plates coated with GST-hVEGF (c, e and g). CIGB-247 combinations using VSSP or aluminum phosphate as adjuvants were administered weekly (eight vaccinations) or bi-weekly (four vaccinations) respectively. Horizontal bars represent the mean values of antibody titer or blocking activity, which are shown for each group. p-Values were calculated according to unpaired t-test. Reference dose (A + V): 400 μg of antigen + 200 μg of VSSP; (¼Ag + ½ V): 100 μg of antigen + 100 μg of VSSP; (¼Ag + V): 100 μg of antigen + 200 μg of VSSP; (Ag + Al): 400 μg of antigen + aluminum phosphate Image collected and cropped by CiteAb from the following publication (https://pubmed.ncbi.nlm.nih.gov/28747172), licensed under a CC-BY license.

Background: VEGFR2/KDR/Flk-1

VEGFR2 (KDR/Flk-1), VEGFR1 (Flt-1) and VEGFR3 (Flt-4) belong to the class III subfamily of receptor tyrosine kinases (RTKs). All three receptors contain seven immunoglobulin-like repeats in their extracellular domains and kinase insert domains in their intracellular regions. The expression of VEGFR1, 2, and 3 is almost exclusively restricted to the endothelial cells. These receptors are likely to play essential roles in vasculogenesis and angiogenesis.

VEGFR2 cDNA encodes a 1356 amino acid (aa) residue precursor protein with a 19 aa residue signal peptide. Mature VEGFR2 is composed of a 745 aa residue extracellular domain, a 25 aa residue transmembrane domain and a 567 aa residue cytoplasmic domain. In contrast to VEGFR1 which binds both PlGF and VEGF with high affinity, VEGFR2 binds VEGF but not PlGF with high affinity.
