Western Blot: PARP Antibody [NSB698] - Western blotting Extracts from Jurkat cells untreated (1, 2) or stimulated with 0.5 µM staurosporine for 3 hours (3, 4) to induce apoptosis were resolved by SDS-PAGE on a 10% polyacrylamide gel and transferred to PVDF. The membrane was blocked with a 5% BSA-TBST buffer overnight at 4 degrees C, and then incubated with the anti-PARP pan (1, 3) or PARP (214/215) cleavage site-specific antibody (CSSA) (2, 4) for two hours at room temperature in a 3% BSA-TBST buffer. After washing, the membrane was incubated with goat F(ab')2 anti-rabbit IgG HRP-conjugate and signals were detected using the Pierce SuperSignal(TM) method. The data show that the PARP (214/215) CSSA only recognizes the 85 kDa fragment of PARP in apoptotic cells (4) and does not react with full length PARP (2), demonstrating the specificity of the antibody. The anti-PARP pan confirms that non-apoptotic cells express full length PARP of 116 kDa (1), which is then cleaved when apoptosis is induced (3).
Immunohistochemistry: PARP Antibody [NSB698] - Immunohistochemistry HeLa cells untreated (A) or induced into apoptosis with 0.5 mM staurosporine for 5 hours (B) and fixed in cold acetone for 5 minutes. Cells were incubated with the PARP (214/215) CSSA at 10 mg/mL. Cells were then incubated with biotinylated goat anti-rabbit IgG followed by ABC (Vector) and DAB. The data show that the PARP (214/215) CSSA specifically recognizes PARP in apoptotic cells. Taken together with Western blot results above, these data demonstrate the specificity of the antibody for cleaved PARP.
