- Western blot analysis of HeLa whole cell lysate using a Caspase-9 polyclonal antibody (Product # PA5-19904) at 1:1000 dilution

- Experimental details
- Western blot analysis was performed on whole cell extracts (30 µg lysate) of U-87 MG (Lane 1), HeLa (Lane 2), HeLa treated with Staurosporine (1uM for 3 hours) (Lane 3), PANC-1 (Lane 4) and A549 (Lane 5). The blot was probed with Anti-Caspase 9 Polyclonal Antibody (Product # PA5-19904, 1:1000 dilution) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/mL, 1:4000 dilution). A 46 kDa band corresponding to Caspase 9 was observed across the cell lines tested and bands at 39 & 37 kDa was also observed corresponding to cleaved Caspase 9.

- Knockdown of Caspase 9 was achieved by transfecting HeLa cells with Caspase 9 specific siRNAs (Silencer® select Product # s2429, s2430). Western blot analysis (Fig. a) was performed using membrane enriched extracts from the Caspase 9 knockdown cells (lane 3), non-specific scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blots were probed with Anti-Caspase 9 Polyclonal Antibody (Product # PA5-19904, 1:1000 dilution) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/mL, 1:4000 dilution). Densitometric analysis of this western blot is shown in histogram (Fig. b). Decrease in signal upon siRNA mediated knock down confirms that antibody is specific to Caspase 9.

- Immunocytochemistry of HeLa cells using Caspase 9 Polyclonal Antibody (Product # PA5-19904) at 5 µg/mL. Cells were fixed with formaldehyde and blocked with 0.1 serum for 1 h at RT; antigen retrieval was by heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody overnight at 4°C. A goat anti-rabbit IgG H&L (HRP) at 1:250 was used as secondary. Counter stained with Hematoxylin.
