ターゲット情報

  • 機能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.
  • 組織特異性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.
  • 配列類似性Belongs to the peptidase C14A family.
    Contains 1 CARD domain.
  • 発生段階Expressed at low levels in fetal heart, at moderate levels in neonate heart, and at high levels in adult heart.
  • 翻訳後修飾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.

  • All lanes : Anti-Caspase-9 antibody [E23] (ab32539) at 1/1000 dilution (purified)

    Lane 1 : HeLa whole cell lysate - treated with Camptothecin
    Lane 2 : HeLa whole cell lysate - untreated

    Lysates/proteins at 10 µg per lane.

    Secondary
    Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/1000 dilution

    Predicted band size : 46 kDa
    Observed band size : 35,46 kDa (why is the actual band size different from the predicted?)

    Blocking and dilution buffer: 5% NFDM/TBST.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human skeltal muscle tissue labelling Caspase-9 with purified ab32539 at 1/250. Heat mediated antigen retrieval was performed using Tris/EDTA buffer pH 9. ab97051, a HRP-conjugated goat anti-rabbit IgG (H+L) was used as the secondary antibody (1/500). Negative control using PBS instead of primary antibody. Counterstained with hematoxylin.

  • Immunocytochemistry/Immunofluorescence analysis of HepG2 cells labelling Caspase-9 with purified ab32539 at 1/500. Cells were fixed with 4% paraformaldehyde and permeabilized with 0.1% Triton X-100. ab150077, an Alexa Fluor® 488-conjugated goat anti-rabbit IgG (1/1000) was used as the secondary antibody. DAPI (blue) was used as the nuclear counterstain. ab7291, a mouse anti-tubulin (1/1000) and ab150120, an Alexa Fluor® 594-conjugated goat anti-mouse IgG (1/1000) were also used.

    Control 1: primary antibody (1/500) and secondary antibody, ab150120, an Alexa Fluor® 594-conjugated goat anti-mouse IgG (1/1000).

    Control 2: ab7291 (1/1000) and secondary antibody, ab150077, an Alexa Fluor® 488-conjugated goat anti-rabbit IgG (1/1000).

A FITC-conjugated goat anti-rabbit IgG (1/500) was used as the secondary antibody. Black - Isotype control, rabbit monoclonal IgG. Blue - Unlabelled control, cells without incubation with primary and secondary antibodies.

  • ab32539 (purified) at 1/80 immunoprecipitating Caspase-9 in HeLa whole cell lysate.

    Lane 2 (+): ab32539 + HeLa whole cell lysate.

    Lane 3 (-): Rabbit monoclonal IgG (ab172730) instead of ab32539 in HeLa whole cell lysate.

    For western blotting, a HRP-conjugated anti-rabbit IgG, specific to the non-reduced form of IgG was used as the secondary antibody (1/1500).

    Blocking buffer and concentration: 5% NFDM/TBST.

    Diluting buffer and concentration: 5% NFDM /TBST.

  • All lanes : Anti-Caspase-9 antibody [E23] (ab32539) at 1/20000 dilution (unpurified)

    Lane 1 : Jurkat cell lysate - untreated
    Lane 2 : Jurkat cell lysate - treated with Camptothecin


    Predicted band size : 46 kDa
    Observed band size : 48 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 28 kDa. We are unsure as to the identity of these extra bands.
  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human cervical carcinoma tissue labelling Caspase 9 with unpurified ab32539 at a dilution of 1/50.

  • Overlay histogram showing K562 cells stained with unpurified ab32539 (red line). The cells were fixed with methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (unpurified ab32539, 1/100 dilution) for 30 min at 22°C. The secondary antibody used was anti-rabbit DyLight® 488 (ab96899) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit monoclonal IgG (1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in K562 cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween used under the same conditions.

As far as we know, rabbits do not have specific IgG subclasses like mice or
humans. All of our antibodies are simply considered to be rabbit IgG.
I hope this is helpful. Please contact me again if you have any further questions.

Je suis vraiment désolé d'apprendre que vous rencontrez un autre problème avec cet anticorps. Pourriez-vous s'il vous plait tester cet anticorps. Si il fonctionne je vous enverrai une nouvelle unité en prenant soin de faire vérifier le tube avant ex...
