Overview

  • Product name
    Anti-VEGFA antibody [JH121]
    See all VEGFA primary antibodies
  • Description
    Mouse monoclonal [JH121] to VEGFA
  • Specificity
    Of the four isoforms of VEGF, the smaller two, VEGF165 and VEGF121, are secreted proteins and act as diffusible agents, whereas the larger two (VEGF189 and VEGF206) remain cell associated. This antibody recognizes all the forms.
  • Tested applications
    Suitable for: IHC-P, IHC-Frmore details
    Unsuitable for: WB
  • Species reactivity
    Reacts with: Mouse, Rat, Rabbit, Human
  • Positive control

Properties

Applications

Our Abpromise guarantee covers the use of ab28775 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P 1/50. Perform heat mediated antigen retrieval via the pressure cooker method before commencing with IHC staining protocol.
IHC-Fr 1/50.
  • Application notes
    Is unsuitable for WB.
  • Target

    • Function
      Growth factor active in angiogenesis, vasculogenesis and endothelial cell growth. Induces endothelial cell proliferation, promotes cell migration, inhibits apoptosis and induces permeabilization of blood vessels. Binds to the FLT1/VEGFR1 and KDR/VEGFR2 receptors, heparan sulfate and heparin. NRP1/Neuropilin-1 binds isoforms VEGF-165 and VEGF-145. Isoform VEGF165B binds to KDR but does not activate downstream signaling pathways, does not activate angiogenesis and inhibits tumor growth.
    • Tissue specificity
      Isoform VEGF189, isoform VEGF165 and isoform VEGF121 are widely expressed. Isoform VEGF206 and isoform VEGF145 are not widely expressed.
    • Involvement in disease
      Defects in VEGFA are a cause of susceptibility to microvascular complications of diabetes type 1 (MVCD1) [MIM:603933]. These are pathological conditions that develop in numerous tissues and organs as a consequence of diabetes mellitus. They include diabetic retinopathy, diabetic nephropathy leading to end-stage renal disease, and diabetic neuropathy. Diabetic retinopathy remains the major cause of new-onset blindness among diabetic adults. It is characterized by vascular permeability and increased tissue ischemia and angiogenesis.
    • Sequence similarities
      Belongs to the PDGF/VEGF growth factor family.
    • Cellular localization
      Secreted. VEGF121 is acidic and freely secreted. VEGF165 is more basic, has heparin-binding properties and, although a signicant proportion remains cell-associated, most is freely secreted. VEGF189 is very basic, it is cell-associated after secretion and is bound avidly by heparin and the extracellular matrix, although it may be released as a soluble form by heparin, heparinase or plasmin.

    • ab28775 staining VEGFA in Human shoulder tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and blocked with 3% serum for 30 minutes at 22°C. Samples were incubated with primary antibody (1/50) for 24 hours at 4°C. A Biotin-conjugated Horse anti-mouse polyclonal (1/1000) was used as the secondary antibody
