  • Application notes
    Is unsuitable for Flow Cyt or ICC/IF.
  • Target

    • Function
      Receptor for VEGF, VEGFB and PGF. Has a tyrosine-protein kinase activity. The VEGF-kinase ligand/receptor signaling system plays a key role in vascular development and regulation of vascular permeability. Isoform SFlt1 may have an inhibitory role in angiogenesis.
    • Tissue specificity
      Mostly in normal lung, but also in placenta, liver, kidney, heart and brain tissues. Specifically expressed in most of the vascular endothelial cells, and also expressed in peripheral blood monocytes. Isoform sFlt1 is strongly expressed in placenta.
    • Sequence similarities
      Belongs to the protein kinase superfamily. Tyr protein kinase family. CSF-1/PDGF receptor subfamily.
      Contains 7 Ig-like C2-type (immunoglobulin-like) domains.
      Contains 1 protein kinase domain.
    • Cellular localization
      Secreted and Cell membrane.

    • Immunohistochemistry (PFA perfusion fixed frozen sections) analysis of mouse brain tissue section (15 days old wild-type mouse embryonic brain, 16 micron) labeling VEGF Receptor 1 with ab32152 at 1/300 dilution. Tissue was fixed with formaldehyde and permeabilized with Triton X100. Heat mediated antigen retrieval was performed using 10mM citrate buffer, pH 6. A polyclonal donkey anti-Rabbit IgG (H+L) (Alexa Fluor® 488) secondary antibody was used at 1/500 dilution.

    • Anti-VEGF Receptor 1 antibody [Y103] (ab32152) at 1/10000 dilution + mouse brain tissue

      Predicted band size : 151 kDa
      Observed band size : 180 kDa (why is the actual band size different from the predicted?)
    • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human abdominal aortic aneurysm (AAA) wall tissue sections labeling VEGF Receptor 1 with ab32152 at 1/100 dilution.

      Resected aortic tissues were immersed in 10% neutral buffered formalin for at least 24 h for immunohistochemical staining. Tissue sample was embedded in paraffin; 4 µm sections were cut and mounted onto MAS-coated slides. The sections were deparaffinized, dehydrated, and boiled in a pressure cooker in 0.01 M citric acid buffer (pH 6.0) for 20 min. The sections were washed with phosphate-buffered saline and incubated with 3% H2O2 in absolute methanol for 5 min to inhibit any endogenous peroxidase activity. Sections were preincubated with 3% normal goat serum for 20 min to minimize nonspecific binding to VEGF Receptor 1, and incubated with ab32152 at 4°C overnight in a moist chamber. The section was washed with phosphate-buffered saline and then incubated with the appropriate secondary antibody for 30 min at room temperature. Staining was visualized with Vector DAB, and tissue section was then counterstained with hematoxylin.
