Specifications

Our Abpromise guarantee covers the use of ab53679 in the following tested applications.

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

  • Biological activity

    The ED50 for stimulation of 3H-thymidine incorporation and cell proliferation by human umbilical vein endothelial cells for VEGFE has been determined to be in the range of 5 - 20 ng/ml. Specific activity: 2 x 105 units/mg.

  • Applications

    SDS-PAGE

  • Purity> 90 % SDS-PAGE.
    Purity: > 90%, by SDS-PAGE and visualised by silver stain. Endotoxin level: < 0.1 ng per ug of VEGFE.
  • FormLyophilised
  • Additional notesLike VEGFA, VEGFE was found to bind with high affinity to VEGF receptor-2 (KDR) resulting in receptor autophosphorylation, whilst in contrast to VEGFA, VEGFE can not bind to VEGF receptor-1 (Flt-1). Furthermore VEGFE can also not bind to VEGF receptor-3 (FLT-4). Therefore VEGFE is a potent angiogenic factor selectively binding to VEGF receptor –2/KDR.

Preparation and Storage

  • Stability and Storage

    Shipped at 4°C. Upon delivery aliquot and store at -20°C or -80°C. Avoid repeated freeze / thaw cycles.

    Preservative: None
    Constituents: PBS, pH 7.4

    This product is an active protein and may elicit a biological response in vivo, handle with caution.

  • ReconstitutionThe lyophilised VEGFE is soluble in water and most aqueous buffers. The lyophilised VEGFE should be reconstituted in PBS or medium containing at least 0.1% human or bovine serum albumin to a concentration not lower than 50 µg/ml.

General Info

  • RelevanceBased on sequence similarity to VEGFA, a gene encoding a VEGF homologue has recently been discovered in the genome of Orf virus (OV) (Lyttle et al., 1994). Different isolates of Orf virus show significant amino acid sequence similarity to VEGFA and described as a viral virulence factor that appears to be derived from captured host genes. All eight cysteine residues of the central cysteine knot motif characteristic of members of the VEGF family are conserved among other residues in the VEGFE proteins (Dehio et al., 1999; Wise et al., 1999). Alignment of all mammalian VEGF sequences indicated that VEGFE is distinct from the previously described VEGFs but most closely related to VEGFA.
