Properties

Applications

Our Abpromise guarantee covers the use of ab25758 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
WB Use a concentration of 1 µg/ml. Detects a band of approximately 45 kDa (predicted molecular weight: 46 kDa).Can be blocked with Mouse Caspase-9 peptide (ab38268).

Target

  • Function
    Involved in the activation cascade of caspases responsible for apoptosis execution. Binding of caspase-9 to Apaf-1 leads to activation of the protease which then cleaves and activates caspase-3. Proteolytically cleaves poly(ADP-ribose) polymerase (PARP).
    Isoform 2 lacks activity is an dominant-negative inhibitor of caspase-9.
  • Tissue specificity
    Ubiquitous, with highest expression in the heart, moderate expression in liver, skeletal muscle, and pancreas. Low levels in all other tissues. Within the heart, specifically expressed in myocytes.
  • Sequence similarities
    Belongs to the peptidase C14A family.
    Contains 1 CARD domain.
  • Developmental stage
    Expressed at low levels in fetal heart, at moderate levels in neonate heart, and at high levels in adult heart.
  • Post-translational
    modifications
    Cleavages at Asp-315 by granzyme B and at Asp-330 by caspase-3 generate the two active subunits. Caspase-8 and -10 can also be involved in these processing events.

Answer

Thank you for contacting us.

As this is an exceptional free of charge replacement, I will process the order. Could you please confirm that you would like a free of charge replacement with ab25758 and not ab133520 (rabbit monoclonal I recommended with a high specificity)?

Unfortunately there is no way of telling how this antibody will work in your experiment apart from trying it. However, please be reassured that this antibody is also covered by our abpromise guarantee.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Answer

Thank you for your enquiry. Further to our telephone conversation this morning I have updated our datasheet regarding the specificity of this antibody for the uncleaved form of Caspase 9. I look forward to reading your Abreview. I have arranged for a free of charge replacement vial of ab25758 to be dispatched immediately (order number: 135138). I hope that this does not affect your choice of Abcam in the future.
