Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 50, 46 kDa (predicted molecular weight: 46 kDa).


  • FunctionInvolved 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 specificityUbiquitous, 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 similaritiesBelongs to the peptidase C14A family.
    Contains 1 CARD domain.
  • Developmental stageExpressed 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.

    Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution
    developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 46 kDa
    Observed band size : 46,50 kDa (why is the actual band size different from the predicted?)

    Exposure time : 5 minutes
    We hypothesize that the 50 and 46 kDa bands represent the pro and mature forms of Caspase 9, respectively. Abcam welcomes customer feedback.
