靶标

  • 功能

    Can induce tyrosine phosphorylation of TIE2. Binds to TIE2 receptor and counteracts blood vessel maturation/stability mediated by angiopoietin-1. Its function may be context-dependent. In the absence of angiogenic inducers, such as VEGF, ANG2-mediated loosening of cell-matrix contacts may induce endothelial cell apoptosis with consequent vascular regression. In concert with VEGF, it may facilitate endothelial cell migration and proliferation, thus serving as a permissive angiogenic signal.

  • 序列相似性

    Contains 1 fibrinogen C-terminal domain.

  • 结构域

    The Fibrinogen C-terminal domain mediates interaction with the TEK/TIE2 receptor.

      Developed using the ECL technique.

      Performed under reducing conditions.

      Predicted band size: 57 kDa
      Observed band size: 52 kDa why is the actual band size different from the predicted?
      Additional bands at: 47 kDa, 65 kDa. We are unsure as to the identity of these extra bands.


      Exposure time: 4 minutes


      The band observed at 52 kDa could potentially be a cleaved form of Angiopoietin 2/ANG2 due to the presence of an 18 amino acid signal peptide.

    Question

    Thank you for the speedy response! I have looked at the two antibodies
    and have decided on ab56301, mainly for the lack of cross reactivity
    with Ang-1.

    Thank you very much for your help! I can't wait to get it!

    Question

    Thank you for getting back to me, and for the good news!
    The most important thing about the Ang-2 antibody that I need is no,
    to VERY little cross reactivity with Ang-1. I am doing studies with
    Ang-2 and Ang-1 and need to be able to distinguish them on separate
    blots. I am using human endothelial cells and the primary usage will
    be Western blots. I don't believe that I will be IP'ing, so
    that is not important.


    Sorry I did not have the ordering information. The number sounds about
    right with their numbering system, but I don't know if that is it
    for sure. I hope that the information provided helps!
    Please let me know if there is anything else needed! I would like to
    get this Ang-2 Antibody and put it to good use!

    Answer

    Thank you for your reply.
    I have aligned the human angiopoietin 1 and 2 proteins and the overall sequence homology is only 61%.
    I would recommend ab64015, since the immunogen does not align well with Ang1 (63% homology)
    https://www.abcam.com/Angiopoietin-2-antibody-ab64015.html
    or ab56301 (https://www.abcam.com/Angiopoietin-2-antibody-MM0020-1F29-ab56301.html) as this antibody recognizes Angiopoietin 2 in western blot without cross reactivity with Angiopoietin 1.
    Please let me know which of the 2 antibodies you would prefer and I will arrange the shipment for you. The order I have is the correct one. Thank you for the additional order information.
    Also, if the shipping address has changed in the meantime (since August), please let me know the new address.
    I look forward to hear back from you.
