Specificity
Stimulation is required to allow detection of the 17kDa cleaved form of the protein. Please see images below for recommended treatment conditions and positive controls.
ab13847 recognizes a cleaved form of Caspase 3 (~17 kDa) after apoptosis has been induced in wildtype cells and not Caspase 3 knockout cells.
Some customers have used this antibody successfully in IHC-P however our latest tests were unsuccessful and therefore we can no longer guarantee this application. We would recommend ab32351 and ab184787 as an alternative product for this application.

Function
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. -
Tissue specificity
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. -
Sequence similarities
Belongs to the peptidase C14A family. -
Post-translational
modificationsCleavage 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. -

Western blot - Anti-Caspase-3 antibody (ab13847)
Lane 1: Wild-type HAP1 cell lysate + Staurosporine (ab146588) (1μM for 4h)
Lane 2: Wild-type HAP1 cell lysate
Lane 3: Caspase-3 knockout HAP1 cell lysate + Staurosporine (ab146588) (1μM for 4h)
Lane 4: Caspase-3 knockout HAP1 cell lysateLanes 1 - 4: Merged signal (red and green). Green - ab13847 observed at 17 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab13847 was shown to recognise Caspase 3 when Caspase 3 knockout samples were used, along with additional cross-reactive bands. Wild-type and Caspase 3 knockout samples (±staurosporine treatment) were subjected to SDS-PAGE. ab13847 and ab8245 (loading control to GAPDH) were diluted to 1/500 and 1/10000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging. -

Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 17, 34 kDa
Observed band size: 17,32 kDa why is the actual band size different from the predicted?
Exposure time: 8 minutesCaspase 3 exist as inactive proenzymes which undergo proteolytic processing at conserved aspartic residues to produce large (17kDa) and small (12kDa) subunits. These subunits dimerize to form the active enzyme. ab13847 specifically detects the large active subunit (17kDa) and the inactive pro Caspase 3 (32 kDa).
This blot was produced using a 4-12% Bis-tris gel under the MES buffer system. The gel was run at 200V for 35 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 5% Bovine Serum Albumin before being incubated with ab13847 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution.
