  • Application notes
    Is unsuitable for ICC or IP.
  • 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

      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.

    • Lanes:
      Lane 1: Wild-type HAP1 whole cell lysate (40 µg).
      Lane 2: CASP9 knockout HAP1 whole cell lysate (40µg).
      Lane 3: HeLa whole cell lysate (40 µg).

      Lanes 1 - 3 Merged signal (red and green). Green - ab32068 observed at 45 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab32068 was shown to specifically recognize CASP9 in wild-type HAP1 cells along with additional cross-reactive bands. No band was observed when CASP9 knockout samples were examined. Wild-type and CASP9 knockout samples were subjected to SDS-PAGE. Ab32068 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1/500 dilution and 1/10,000 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 1/10,000 dilution for 1 hour at room temperature before imaging.
