Application Abreviews Notes
ICC/IF 1/250.
IP 1/120.
WB 1/5000. Detects a band of approximately 35, 32, 27, 11 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.

  • Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized NIH/3T3 (Mouse embyro fibroblast cells) cells labeling Caspase-7 with ab181579 at 1/250 dilution, followed by Goat anti-rabbit IgG (Alexa Fluor® 488) (ab150077) secondary antibody at 1/400 dilution (green). Cytoplasm and nuclear staining on NIH/3T3 cell line is observed. The nuclear counter stain is DAPI (blue). Tubulin is detected with ab7291 (anti-Tubulin mouse mAb) at 1/500 dilution and ab150120 (AlexaFluor®594 Goat anti-Mouse secondary) at 1/500 dilution (red).
    The negative controls are as follows:
    1. ab181579 at 1/250 dilution followed by ab150120 (AlexaFluor®594 Goat anti-Mouse secondary) at 1/500 dilution.
    2. ab7291 (anti-Tubulin mouse mAb) at 1/500 dilution followed by ab150077 (Alexa Fluor®488 Goat Anti-Rabbit IgG H&L) at 1/400 dilution.

  • Caspase-7 was immunoprecipitated from 1mg of NIH/3T3 (Mouse embyro fibroblast cells) with ab181579 at 1/120 dilution. Western blot was performed from the immunoprecipitate using ab181579 at 1/1000 dilution. Anti-Rabbit IgG (HRP), specific to the non-reduced form of IgG, was used as secondary antibody at 1/1500 dilution.

    Lane 1: NIH/3T3 whole cell extract. Lane 2: PBS instead of extract.

    Blocking/Dilution buffer: 5% NFDM/TBST.

    The observed band at 35kDa band is the pro-caspase-7.
