Western blot - Anti-Caspase-8 antibody [E6] (AB32125)

Lanes 1 and 2 : Merged signal (red and green). Green - ab32125 observed at 55 kDa. Red - loading control, ab8226, observed at 42 kDa.

ab32125 was shown to recognize Caspase-8 when Caspase-8 knockout samples were used, along with additional cross-reactive bands. Wild-type and Caspase-8 knockout samples were subjected to SDS-PAGE. ab32125 and ab8226 (loading control to beta actin) were diluted 1/3000 and 1/1000 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 1/10 000 dilution for 1 h at room temperature before imaging.

Western blot - Anti-Caspase-8 antibody [E6] (AB32125)

Lanes 1- 4 : Merged signal (red and green). Green - ab32125 observed at 55 kDa. Red - Anti-GAPDH antibody [6C5] - Loading Control (ab8245) observed at 37 kDa.

ab32125 was shown to react with Caspase-8 in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab264958 (knockout cell lysate ab256857) was used. Wild-type HeLa and CASP8 knockout HeLa cell lysates were subjected to SDS-PAGE. Membrane was blocked for 1 hour at room temperature in 0.1% TBST with 3% non-fat dried milk. ab32125 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) overnight at 4°C at a 1 in 3000 dilution and a 1 in 20000 dilution respectively. 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 in 20000 dilution for 1 hour at room temperature before imaging.

Western blot - Anti-Caspase-8 antibody [E6] (AB32125)

Western blot : Anti-Caspase-8 antibody [E6] ab32125 staining at 1/3000 dilution, shown in green; Mouse anti GAPDH (ab8245) loading control staining at 1/20,000 dilution, shown in magenta. A band was observed at 60 kDa in Wild-type A549 cell lysates with no signal observed at this size in CASP8 knockout A549 cell line. To generate this image, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 5pc Milk in TBS-0.1 % Tween^® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit 800CW & Goat anti-Mouse 680RD at 1/20,000 dilution.
