Experimental details

Western blot analysis was performed on whole cell extracts (20 µg lysate) of HeLa (lane1), Jurkat (lane2), Jurkat treated Calyculin A (50 ng/mL/20 min) (lane3), K562 (lane4) and K562 treated with Calyculin A (50 ng/mL/20 min) (lane5). The blots were probed with Anti-IRF3 (pS396)Rabbit Polyclonal Antibody (Product # 720012, 0.5-2 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 55 kDa band corresponding to IRF3 (pS396) was observed across cell lines tested according to the treatment. 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

Immunofluorescence was performed on fixed and permeabilized HeLa cells treated with Calyculin A (50 ng/mL/20 min) for detection of IRF-3 (pS396) using Anti-IRF-3 (pS396)Rabbit Polyclonal Antibody (Product # 720012, 2 µg/mL) and labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034, 0.4 µg/mL, 1:2500). Panel a) shows representative cells that were stained for detection and localization of IRF-3 (pS396) protein (green), Panel b) is stained for nuclei (blue) using SlowFade® Gold Antifade Mountant with DAPI (Product # S36938, 1:50). Panel c) represents cytoskeletal F-actin staining using Alexa Fluor® 594 Phalloidin (Product # A12381, 1:200). Panel d) is a composite image of Panels a, b and c clearly demonstrating nuclear localization of IRF-3 (pS396). Panel e) represents control cells with no primary antibody to assess background.

Experimental details

Flow Cytometry analysis of IRF-3 [pS396] was performed on Jurkat cells treated with Calyculin A (50ng/ml/ 20 min) cells labeled with IRF-3 [pS396] Rabbit Polyclonal Antibody (Product# 720012, 2-4 ug/ 1M cells) or with rabbit isotype control and detected with Goat anti-Rabbit IgG (H+L) Superclonalª Secondary Antibody, Alexa Fluor¨ 488 conjugate (Product # A27034, 0.4 ug/ml, 1:2500) as represented by the red and pink histograms respectively. The purple histogram represents unstained control cells and the green histogram represents no-primary-antibody control. A representative 10,000 cells were acquired and analyzed for each sample using an Attune¨ Acoustic Focusing Cytometer (4468770).
