Properties

Applications

Our Abpromise guarantee covers the use of ab13585 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 - 5 µg/ml. Predicted molecular weight: 31 kDa. The antibody detects both pro Caspase 3 (~32 kDa) and the large subunit of the active/cleaved form (~14-21 kDa) of Caspase 3. The large subunit of the cleaved form may appear as one or two or even as a stack of bands depending on the presence or absence of the Caspase 3 pro-domain.

Target

  • FunctionInvolved in the activation cascade of caspases responsible for apoptosis execution. At the onset of apoptosis it proteolytically cleaves poly(ADP-ribose) polymerase (PARP) at a '216-Asp-
    -Gly-217' bond. Cleaves and activates sterol regulatory element binding proteins (SREBPs) between the basic helix-loop-helix leucine zipper domain and the membrane attachment domain. Cleaves and activates caspase-6, -7 and -9. Involved in the cleavage of huntingtin.
  • Tissue specificityHighly expressed in lung, spleen, heart, liver and kidney. Moderate levels in brain and skeletal muscle, and low in testis. Also found in many cell lines, highest expression in cells of the immune system.
  • Sequence similaritiesBelongs to the peptidase C14A family.
  • Post-translational
    modifications
    Cleavage by granzyme B, caspase-6, caspase-8 and caspase-10 generates the two active subunits. Additional processing of the propeptides is likely due to the autocatalytic activity of the activated protease. Active heterodimers between the small subunit of caspase-7 protease and the large subunit of caspase-3 also occur and vice versa.
    S-nitrosylated on its catalytic site cysteine in unstimulated human cell lines and denitrosylated upon activation of the Fas apoptotic pathway, associated with an increase in intracellular caspase activity. Fas therefore activates caspase-3 not only by inducing the cleavage of the caspase zymogen to its active subunits, but also by stimulating the denitrosylation of its active site thiol.

  • Predicted band size : 31 kDa
    Additional bands at : 32 kDa. We are unsure as to the identity of these extra bands.

    Lane 1: Wild-type HAP1 cell lysate + Staurosporine (1μM for 4h)
    Lane 2: Wild-type HAP1 cell lysate
    Lane 3: Caspase-3 knockout HAP1 cell lysate + Staurosporine (1μM for 4h)
    Lane 4: Caspase-3 knockout HAP1 cell lysate
    Lanes 1 - 4: Merged signal (red and green). Green - ab13585 observed at 32 kDa. Red - loading control, ab181602, observed at 37 kDa.

    ab13585 was shown to recognise pro Caspase 3 when Caspase 3 knockout samples were used, along with additional cross-reactive bands. Wild-type and Caspase 3 knockout samples (± Staurosporine treatment) were subjected to SDS-PAGE. ab13585 at a concentration of 1 µg/ml and ab8245 (loading control to GAPDH) diluted to 1/10000 were incubated overnight at 4°C. Blots were developed with goat anti-rabbit IgG (H + L) and goat anti-mouse IgG (H + L) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.



  • Predicted band size : 31 kDa

    Western blot analysis of Caspase 3 in HeLa cells using ab13585. Cells were treated with 2 uM staurosporine for different time periods. Caspase 3 activation is detected in Western blots by the presence of Caspase 3 cleavage fragments.

    ab13585 detected both pro (full-length) and active (cleaved) Caspase 3, depending on the treatment time points. Pro Caspase 3 is detected at ~32 kDa. Active/cleaved Caspase 3 (large subunit) is detected at ~14-21 kDa as one or more bands.

    This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using Licor blocking buffer before being incubated with ab13585 overnight at 4°C. Antibody binding was detected using ab175781 at a 1:10,000 dilution for 1hr at room temperature and then imaged using the Licor Odyssey CLx.
