Anti-pro Caspase 7 antibody [Y33] (ab32067)


  • Product name
    Anti-pro Caspase 7 antibody [Y33]
  • Description
    Rabbit monoclonal [Y33] to pro Caspase 7
  • Specificity
    The antibody only recognizes the pro-form of Caspase-7. It does not react with the cleaved forms (active enzyme) of Caspase-7.
  • Tested applications
    Suitable for: WB, IHC-P, ICC/IFmore details
    Unsuitable for: Flow Cyt or IP
  • Species reactivity
    Reacts with: Human
  • Immunogen

    A synthetic peptide corresponding to N-terminal residues of human Pro-Caspase-7.

  • Positive control
    • Jurkat cell lysate and human lung squamous carcinoma.

Our Abpromise guarantee covers the use of ab32067 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 1/1000. Detects a band of approximately 34 kDa (predicted molecular weight: 34 kDa).
IHC-P 1/50.
ICC/IF 1/50.
  • Application notes
    Is unsuitable for Flow Cyt or IP.
  • Target

    • 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.

      ab32067 was shown to recognize pro Caspase 7 when HAP1 + pro Caspase 7 knockout samples were used, along with additional cross-reactive bands. Wild-type and pro Caspase 7 knockout samples were subjected to SDS-PAGE. Ab32067 and ab18058 (Mouse anti-Vinculin loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
