Our Abpromise guarantee covers the use of ab25900 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 Use a concentration of 2 µg/ml.
WB Use a concentration of 0.5 µg/ml. Detects a band of approximately 30 kDa (predicted molecular weight: 34 kDa).


  • Function

    Involved in the activation cascade of caspases responsible for apoptosis execution. Cleaves and activates sterol regulatory element binding proteins (SREBPs). Proteolytically cleaves poly(ADP-ribose) polymerase (PARP) at a '216-Asp-
    -Gly-217' bond. Overexpression promotes programmed cell death.
  • Tissue specificity

    Highly expressed in lung, skeletal muscle, liver, kidney, spleen and heart, and moderately in testis. No expression in the brain.
  • Sequence similarities

    Belongs to the peptidase C14A family.
  • Post-translational

    Cleavages by granzyme B or caspase-10 generate the two active subunits. Propeptide domains can also be cleaved efficiently by caspase-3. Active heterodimers between the small subunit of caspase-7 and the large subunit of caspase-3, and vice versa, also occur.

Thank you for your enquiry. With regards to specificity of this antiserum we are satisfied that it recognizes the murine homolog of the epitope, albeit as determined by western blotting. Unfortunately on this occasion I cannot offer you a free vial. However, if you decide to go ahead and purchase this product, please let us know how you get on by submitting an Abreview and in return we will award you 50 Abcam Points, which can be redeemed on a number of rewards (a further 100 Abcam Points will be offered for an image).

Thank you for your enquiry. Further to correspondence with the source of this antiserum, I have determined that with respect to murine cells, ab25900 has only been tested by western blotting. IHC testing at this time has only been performed on paraffin-embedded HUMAN tissues. I hope this information helps, please do not hesitate to contact me should you require further assistance.
