- Description
- PA1-186 has been successfully used in WB using StartingBlock T20 (TBS) Blocking Buffer (Product # 37543). More non-specific bands are observed when using 5% BSA for blocking. By WB, PA1-186 detects a predominant band at 65kD. Loading increasing amounts of cell lysate may yield more intense nonspecific bands at ~120kD and/or ~50kD. PA1-186 has been succesfully used for IP of the NF-kB p65 subunit and co-IP of the NF-kB p50 subunit.

- Knockdown of NFkB p65 was achieved by transfecting HeLa with NFkB p65 specific siRNAs (Silencer® select Product # s11916, s11914). Western blot analysis was performed using Nuclear enriched extracts from the NFkB p65 knockdown cells (lane 3), scrambled siRNA transfected cells (lane 2), and untransfected cells (lane 1). The blot was probed with NFkB p65 Polyclonal Antibody (Product # PA1-186, 1 µg/mL) and Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036, 1:20000 dilution). Decrease in signal upon siRNA mediated knock down confirms that antibody is specific to NFkB p65.

- Western blot analysis was performed on whole cell extracts (20 µg lysate) of NIH/3T3 (Lane 1), MCF7 (Lane 2), Hep G2 (Lane 3), Jurkat (lane 4) and HeLa (lane 5). The blots were probed with Anti-NF-kB p65 Rabbit Polyclonal Antibody (Product # PA1-186, 1-3 µg/mL) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.4 µg/mL, 1:2500 dilution). A 60 kDa band corresponding to NF-kB p65 was observed across cell lines tested. 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® 2 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).

- Flow cytometry analysis of NF-kappa B p65 was done on HeLa cells. Cells were fixed with 70% ethanol for 10 minutes, permeabilized with 0.25% Triton™ X-100 for 20 minutes, and blocked with 5% BSA for 30 minutes at room temperature. Cells were labeled with NF-kappa B p65 Rabbit Polyclonal Antibody (PA1186, red histogram) or with rabbit isotype control (pink histogram) at 3-5 ug/million cells in 2.5% BSA. After incubation at room temperature for 2 hours, the cells were labeled with Alexa Fluor® 488 Goat Anti-Rabbit Secondary Antibody (A11008) at a dilution of 1:400 for 30 minutes at room temperature. The representative 10,000 cells were acquired and analyzed for each sample using an Attune® Acoustic Focusing Cytometer. The purple histogram represents unstained control cells and the green histogram represents no-primary-antibody control.

Seven-day-old rats were subjected to sham surgery or to ligation of the right carotid artery followed by hypoxia (HI) alone or with subsequent injection of melatonin (10 mg/kg; HI + melatonin (MEL). Animals were sacrificed after 24 h. Double immunohistochemical staining of Iba1 (red) and NF-kB (green) with DAPI nuclear counterstaining (blue) is shown. The graph reports the percentage of nuclear SIRT1+, Iba1+ microglial cells in the area. Representative images of ipsilateral CC are shown. Arrows indicate representative Iba+ cells with nuclear NF-kB; arrowheads indicate representative Iba1+ cells with extranuclear NF-kB staining. Asterisks indicate cells reported in the insets at higher magnification. Scale bar = 40 mum.
