    • 機能

      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.
    • 組織特異性

      Isoform VEGF189, isoform VEGF165 and isoform VEGF121 are widely expressed. Isoform VEGF206 and isoform VEGF145 are not widely expressed.
    • 関連疾患

      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.
    • 配列類似性

      Belongs to the PDGF/VEGF growth factor family.
    • 細胞内局在

      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.

      Human embryonic stem cells (H9) were differentiated both as embryoid bodies and monolayer cultures (on Matrigel) using a protocol described in Kennedy et al., 2006. BMP-4, FGF-basic (ab9596) and VEGF (ab9571) were sequentially added to the media to direct differentiation. These images were taken at day 8, where cell adhesion antigens CD31 (ab32457 in green) and CD34 (ab8536 in red) are abundant and represent primitive haematopoietic cells within the culture. DAPI staining is shown in blue.

    Question

    I have a scaffold that contains sulfated glycoaminoglycans (GAGs). GAGs can bind VEGF in vivo. I need to absorb VEGF to these scaffolds so the first question is if VEGF ab9571 binds to GAGs in its form (Is it a dimer? Does it have the GAG attachment cites etc.).
    After, I need to immuno-stain the VEGF with the proper antibody ab 1316 and take pictures using fluorescent microscope. So the second question is whether ab1316 will stain VEGF ab9571.
    After, I would like to stimulate HUVEC with VEGF ab9571. So the third question is whether this form of VEGF ab9571 will properly stimulate these cells.

    Asked on Oct 30 2013

    Answer

    The Active human VEGF full length protein (ab9571) has been tested on HUVECs and is known to stimulate proliferation of these cells, which shows that the GAG sites are present and active.
    The recombinant human VEGF165 is a 38.2 kDa disulfide-linked homodimeric protein consisting of two 165 amino acid polypeptide chains. Unfortunately, we cannot be certain on where exactly the GAG sites are present. However, because ab9571 has been tested on HUVECs and does stimulate proliferation we would think that the GAG sites are present and active. Please be aware that anyhow we cannot guarantee it.
    The Anti-VEGF antibody [VG-1] (ab1316) is able to detect Active human VEGF full length protein (ab9571) because ab9571 is VEGF 165 and ab1316 is able to detect VEGF 165 (please refer to the antibody datasheet for more information).

    Answer

    Thank you for contacting us and for your patience.

    I had to contact the laboratory in order to get more information about the use of these three proteins.

    I can confirm, that for the ab92965 SPARC protein (MBP) to our knowledge it has not been tested for injection in mice or other animals (besides it uses as immunogen for polyclonal antibodies production in rabbits intramuscular). It could be that it will work for injection in mice but we can not guarantee this and we have no information about different administration routes (intravenous, intramuscular etc.).

    The two other proteins have been used in mice before. See the following links:

    Answer

    Thank you for contacting us and your interest in our products.

    We have a few different products which may be of interest to your customer. Proteins ab61861, ab56620 and ab83572 are all of the VEGF 165A form. Additionally, ab61861 and ab83572 have both been shown to have biological activity as measured by using a HUVEC assay. I think these two may therefore be of most interest to your customer.

    I hope this information has been of help. If you require any further information, please do not hesitate to contact us again.

    Question

    I am interested in VEGF165 (recombinant expressed in E. coli) as well as in an Anti-VEGF-antibody. I would like to do conformation analysis and I need the mature VEGF-protein with length of 165 amino acids. So there should be no N-terminal signal sequence.

    You offer these three VEGF165 proteins: ab56620, ab61861, ab9571 and I wonder which of your products is the right one for me. Do ab56620 and ab61861 contain 165 or 191 aa?

    Further which antibody (preferred host: rabbit) do you recommend to detect the mentioned proteins?

    Can you give me any further sequence information about the target proteins of following antibodies: ab52917, ab9570, ab99511?

    Verified customer

    Asked on Mar 29 2012

    Answer

    Thank you for contacting us.

    For the proteins, I would suggest using ab61861 as this protein is arecombinant Human VEGF 165A protein (double, non-glycosylated, polypeptide chain containing 165 amino acids, MW 38kDa, expressed in E.coli).

    In terms of the most suitable antibodies, ab9570 which is reactive with VEGF 165and 121, would be the best choice. It was raised against highly pure (>98%) recombinant hVEGF 165 (human Vascular Endothelial Cell Growth Factor), however, the epitope has not been mapped.

    As for ab52917 and ab99511, I willcontact the lab to obtain more information about the immunogen region. As soon as I have more details, I will let you know.

    What kind of conformation studies are you planning to do? As far as I can tell such application has not been tried with neither these protein nor antibodies.

    I hope this information is already of some help to you.
    In the meantime, please do not hesitate to contact us if you need any more advice or information.

If I added this VEGF protein to HUVEC cells in culture an I correct in thinki8ng that it would signal through VEGFR2 and thus would phosphorylate this receptor tyrosine kinase?
