Overlay histogram showing K562 cells stained with unpurified ab32539 (red line). The cells were fixed with methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (unpurified ab32539, 1/100 dilution) for 30 min at 22°C. The secondary antibody used was anti-rabbit DyLight^® 488 (ab96899) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit monoclonal IgG (1μg/1x10⁶ cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in K562 cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween used under the same conditions.

Immunoprecipitation - Anti-Caspase-9 antibody [E23] - BSA and Azide free (AB219590)

ab32539 (purified) at 1/80 immunoprecipitating Caspase-9 in HeLa whole cell lysate.

Lane 1 (input) : HeLa whole cell lysate (10µg)

Lane 2 (+) : ab32539 + HeLa whole cell lysate.

Lane 3 (-) : Rabbit monoclonal IgG (ab172730) instead of ab32539 in HeLa whole cell lysate.

For western blotting, a HRP-conjugated anti-rabbit IgG, specific to the non-reduced form of IgG was used as the secondary antibody (1/1500).

Blocking buffer and concentration : 5% NFDM/TBST.

Diluting buffer and concentration : 5% NFDM /TBST.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab32539).

Western blot - Anti-Caspase-9 antibody [E23] - BSA and Azide free (AB219590)

False colour image of Western blot : Anti-Caspase-9 antibody [E23] staining at 1/1000 dilution, shown in green; Mouse anti-CANX [CANX/1543] (ab238078) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab32539 was shown to bind specifically to Caspase-9. A band was observed at 45 kDa in wild-type THP-1 cell lysates with no signal observed at this size in CASP9 knockout cell line ab276122 (knockout cell lysate ab284219). To generate this image, wild-type and CASP9 knockout THP-1 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % 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 IgG H&L (IRDye^® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed (ab216776) at 1/20000 dilution.

mTOR inhibitors combined with glycolysis inhibitor induced apoptosis in lung cancer cells.(a) A549 cells were pretreated with 5 mM 2DG for 1 h, and then cells were treated with 8 μM rapamycin or 5 μM AZD2014 for additional 48 h respectively, cell apoptosis was then examined by using an Annexin V-FITC/PI staining assay kit. (b) A549 cells were pretreated with 5 mM 2DG for 1 h, and then treated with 5 μM AZD2014 for additional 48 h, as well as the cells were untreated and treated with 5 mM 2-DG or 5 μM AZD2014 alone for 48 h before harvesting cellular proteins. (c) A549 cells were pretreated with 5 mM 2DG for 1 h, and then treated with 5 μM AZD2014 for additional 48 h. Meanwhile, the cells were untreated and treated with 5 mM 2DG or 5 μM AZD2014 alone for 48 h before harvesting cellular proteins. All cell lysates were probed for the apoptosis–associated proteins such as BAX, BCL-2, cleaved PARP, cleaved caspase-3 and caspase 9 by Western blot. The similar results were obtained from other two independent experiments, and data shown are the representatives of the three experiments.
