  • 製品の詳細
    Rabbit monoclonal [E83-77] to active Caspase-3
  • 特異性
    Mouse, Rat: We have preliminary internal testing data to indicate this antibody may not react with these species. Please contact us for more information This antibody only detects the active (cleaved) form of Caspase-3 and does not recognize the pro form of Caspase-3. PubMedID 19789217 describes the detection of human cells injected into mice.

  • ターゲット情報

    • 機能
      Involved in the activation cascade of caspases responsible for apoptosis execution. At the onset of apoptosis it proteolytically cleaves poly(ADP-ribose) polymerase (PARP) at a '216-Asp-
      -Gly-217' bond. Cleaves and activates sterol regulatory element binding proteins (SREBPs) between the basic helix-loop-helix leucine zipper domain and the membrane attachment domain. Cleaves and activates caspase-6, -7 and -9. Involved in the cleavage of huntingtin. Triggers cell adhesion in sympathetic neurons through RET cleavage.
    • 組織特異性
      Highly expressed in lung, spleen, heart, liver and kidney. Moderate levels in brain and skeletal muscle, and low in testis. Also found in many cell lines, highest expression in cells of the immune system.
    • 配列類似性
      Belongs to the peptidase C14A family.
    • 翻訳後修飾
      Cleavage by granzyme B, caspase-6, caspase-8 and caspase-10 generates the two active subunits. Additional processing of the propeptides is likely due to the autocatalytic activity of the activated protease. Active heterodimers between the small subunit of caspase-7 protease and the large subunit of caspase-3 also occur and vice versa.
      S-nitrosylated on its catalytic site cysteine in unstimulated human cell lines and denitrosylated upon activation of the Fas apoptotic pathway, associated with an increase in intracellular caspase activity. Fas therefore activates caspase-3 not only by inducing the cleavage of the caspase zymogen to its active subunits, but also by stimulating the denitrosylation of its active site thiol.

      Lanes 1 - 6: Merged signal (red and green). Green - ab32042 observed at 17 kDa. Red - loading control, ab8245, observed at 130 kDa.

      ab32042 was shown to specifically react with CASP3 (Caspase-3) when CASP3 (Caspase-3) knockout samples were used. HAP1 wild-type and CASP3 (Caspase-3) knockout samples were subjected to SDS-PAGE. Ab32042 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 500 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 1/10000 dilution for 1 hour at room temperature before imaging.

      Cells were grown to confluency prior to treatment.

    Thank you for your enquiry.

    I would not recommend using an autoclave, as this could damage the tissue. I would suggest using a pressure cooker or a microwave. The time and temperature may require some optimization. For the time, I can suggest...
