Flow Cytometry of HUVEC Cells Stained with PerCP Conjugated VEGF Antibody

Analysis of PerCP conjugate of NB100-664. An intracellular stain was performed on HUVEC cells with VEGF (VG1) antibody NB100-664PCP (blue) and a matched isotype control NBP2-27287PCP (orange). Cells were fixed with 4% PFA and then permeablized with 0.1% saponin. Cells were incubated in an antibody dilution of 10 ug/mL for 30 minutes at room temperature. Both antibodies were directly conjugated to PerCP.

Application Notes
In IHC a dilution of 1:20-1:50 was used in an ABC method. However, depending on the staining conditions employed, we suggest that the final dilution should be determined by the user. We suggest an incubation period of 30-60 minutes at room temperature. High temperature treatment of formalin-fixed tissue sections using 1mM EDTA, pH 8.0 must be performed prior to the immunostaining. This antibody is CyTOF ready.

Background: VEGF

Vascular endothelial growth factor (VEGF), also called VEGF-A and vascular permeability factor (VPF), is a secreted homodimeric glycoprotein belonging to the VEGF family with a role in stimulating angiogenesis and vasculogenesis (1,2). More specifically, VEGF-A secretion from most cell types contributes to promoting endothelial cell proliferation and migration, inhibiting apoptosis, increasing vascular permeability, and wound healing (1). The VEGF family consists of several members including VEGF-A, VEGF-B, VEGF-C, VEGF-D, VEGF-E, VEGF-F, and placenta growth factor (PLGF) (1-4). As a result of alternative splicing of the eight exon VEGFA gene, there are several VEGF-A protein isoforms of 121, 145, 165, 183, 189, and 206 amino acids (aa) in length, with VEGF121 and VEGF165 being the two most expressed isoforms (1,5). Full length VEGF-A monomer has a 26 aa signal sequence plus a 206 aa (VEGF206) sequence, with a theoretic molecular weight (MW) of 27 kDa, containing VEGF receptor 1 (VEGFR1) and VEGR2 binding sites and heparin-binding domains (1-3,5,6). VEGF121 lacks heparin affinity and binds the receptor tyrosine kinases (RTKs) VEGFR1 and VEGFR2, whereas VEGF165 has moderate affinity for heparin and, in addition to being a ligand for VEGFR1 and VEGFR2, can also bind the co-receptors neuropilin 1 (NRP1) and NRP2 (1,5). Hypoxia and hypoxia-related genes such as HIF-1, EGF, and PDGF are major regulators angiogenesis and VEGF expression (1,3). VEGF signaling initiated by ligand binding to its receptors results in activation of different pathways including PI3K and MAPK and ultimately guides endothelial cell proliferation, migration, and survival (1,3). While VEGF plays an important role in promoting normal angiogenesis and blood vessel formation, its expression is often upregulated in tumors and other angiogenesis-related pathologies like osteroarthritis (OA) (1-5,7). Given its function, VEGF and its receptors have become a therapeutic target for treating cancer and blocking angiogenesis (4,5,7). A recombinant humanized monoclonal anti-VEGFA antibody called bevacizumab (Avastin) was first approved by the FDA in 2004 for the treatment of a number of cancers (1-3,5). Cancer patients may experience resistance to anti-VEGF antibodies and, as such, clinical studies are exploring combination treatment options with chemotherapies and immune-checkpoint inhibitors (3,5).
