Anti-Caspase-3 抗体 [31A1067] (ab13585)

Lane 1: Wild-type HAP1 cell lysate + Staurosporine (1μM for 4h)
Lane 2: Wild-type HAP1 cell lysate
Lane 3: Caspase-3 knockout HAP1 cell lysate + Staurosporine (1μM for 4h)
Lane 4: Caspase-3 knockout HAP1 cell lysate
Lanes 1 - 4: Merged signal (red and green). Green - ab13585 observed at 32 kDa. Red - loading control, ab181602, observed at 37 kDa.

ab13585 was shown to recognise pro 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. ab13585 at a concentration of 1 µg/ml and ab8245 (loading control to GAPDH) diluted to 1/10000 were incubated overnight at 4°C. Blots were developed with Goat anti-Mouse IgG H&L (IRDye^® 800CW) preadsorbed (ab216772) and Goat Anti-Rabbit IgG H&L (IRDye^® 680RD) preadsorbed (ab216777) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

Western blot analysis of Caspase 3 in HeLa cells using ab13585. Cells were treated with 2 uM staurosporine for different time periods. Caspase 3 activation is detected in Western blots by the presence of Caspase 3 cleavage fragments.

ab13585 detected both pro (full-length) and active (cleaved) Caspase 3, depending on the treatment time points. Pro Caspase 3 is detected at ~32 kDa. Active/cleaved Caspase 3 (large subunit) is detected at ~14-21 kDa as one or more bands.

This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using Licor blocking buffer before being incubated with ab13585 overnight at 4°C. Antibody binding was detected using ab175781 at a 1:10,000 dilution for 1hr at room temperature and then imaged using the Licor Odyssey CLx.
