Experimental details

Western blot analysis was performed on whole cell extracts (30 µg lysate) of PC-3 (Lane 1), PC-3 treated with Neocarzinostatin (200 ng/mL for 30 min) (Lane 2). The blots were probed with Anti-phospho-KAP1 (pS824) Recombinant Rabbit Polyclonal Antibody (Product # 711116, 1-2 µg/mL). A 110 kDa band corresponding to KAP1 (pS824) was observed upon Neocarzinostatin treatment. The blots were detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.4 µg/mL, 1:5000 dilution). Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 4-12% Bis-Tris gel (Product # NP0321BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary Antibody following blocking with 5% skimmed milk. Chemiluminescent detection was performed using Pierce™ ECL Western blotting Substrate (Product # 32106).

Experimental details

For immunofluorescence analysis, HeLa cells were fixed and permeabilized for detection of endogenous KAP1 pS824 using Anti-KAP1 pS824 Recombinant Rabbit Polyclonal Antibody (Product # 711116, 2 µg/mL) and labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034, 1:2000). Nuclei (blue) were stained using SlowFade® Gold Antifade Mountant with DAPI (Product # S36938), and Rhodamine Phalloidin (Product # R415, 1:300) was used for cytoskeletal F-actin (red) staining. Detection and localization of KAP1 pS824 (green) in the nucleus can be clearly observed in cells treated with Neocarzinostatin (200 ng/mL, 15 min) as compared to untreated cells. Antibody specificity was demonstrated by competition with the KAP1 pS824 peptide, which results in loss of signal. No competition was observed with the non-phospho peptide. The images were captured at 60X magnification.

Experimental details

Flow Cytometry analysis of endogenous KAP1 (pS824) was performed on HeLa cells (untreated) and HeLa cells treated with 200 ng/mL Neocarzinostatin for 30 minutes. Cells were labeled with Anti-KAP1 (pS824) Recombinant Rabbit Polyclonal Antibody (Product # 711116, 5 µg/ 1M cells) and detected with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, (Alexa Fluor® 488 conjugate, Product # A27034, 0.4 µg/mL, 1:2500). Rabbit IgG was used as the isotype control to determine nonspecific binding. A representative of 10,000 cells were acquired and analyzed for each sample using an Attune® Acoustic Focusing Cytometer (Product # 4468770).
