  Western blot - Anti-Caspase-3 antibody [E87] - BSA and Azide free (ab197202)

  Lanes 1 - 4: Merged signal (red and green). Green - Anti-Caspase-3 antibody [E87] ab32351 observed at 31 kDa. Red - loading control, Anti-Vinculin antibody [VIN-54] ab130007, observed at 130 kDa.
  

  Anti-Caspase-3 antibody [E87] ab32351 was shown to recognize Caspase 3 in wild-type HAP1 cells as signal was lost at the expected MW in HAP1 Staurosporine Treated (CASP3) knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and HAP1 Staurosporine Treated (CASP3) knockout samples were subjected to SDS-PAGE. Anti-Caspase-3 antibody [E87] ab32351 and Anti-Vinculin antibody [VIN-54] ab130007 (Mouse anti-Vinculin loading control) were incubated overnight at 4°C at 1/5000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Caspase-3 antibody [E87] - BSA and Azide free (ab197202)

  This IHC data was generated using the same anti-Caspase 3 antibody clone, E87, in a different buffer formulation (cat# Anti-Caspase-3 antibody [E87] ab32351).
  

  Immunohistochemical staining of paraffin embedded human tonsil with purified Anti-Caspase-3 antibody [E87] ab32351 at a working dilution of 1/100. The secondary antibody used is HRP goat anti-rabbit IgG H&L (Goat Anti-Rabbit IgG H&L (HRP) ab97051) at 1/500. The sample is counter-stained with hematoxylin. Antigen retrieval was perfomed using Tris-EDTA buffer, pH 9.0. PBS was used instead of the primary antibody as the negative control, and is shown in the inset.

The secondary antibody was Alexa Fluor^® 488 goat anti-rabbit (Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) ab150077), used at a dilution of 1/1000. Anti-alpha Tubulin antibody [DM1A] - Loading Control ab7291, a mouse anti-tubulin antibody (1/1000), was used to stain tubulin along with Goat Anti-Mouse IgG H&L (Alexa Fluor® 594) preadsorbed ab150120 (Alexa Fluor^® 594 goat anti-mouse, 1/1000), shown in the top right hand panel. The cells were fixed in 4% PFA and permeabilized using 0.1% Triton X 100. The negative controls are shown in bottom middle and right hand panels - for negative control 1, purified Anti-Caspase-3 antibody [E87] ab32351 was used at a dilution of 1/500 followed by an Alexa Fluor^® 594 goat anti-mouse antibody (Goat Anti-Mouse IgG H&L (Alexa Fluor® 594) preadsorbed ab150120) at a dilution of 1/500. For negative control 2, Anti-alpha Tubulin antibody [DM1A] - Loading Control ab7291 (mouse anti-tubulin) was used at a dilution of 1/500 followed by an Alexa Fluor^® 488 goat anti-rabbit antibody (Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) ab150077) at a dilution of 1/400.
