Experimental details: Western blot analysis of 14-3-3 zeta was performed by loading 30 µg of THP-1 whole cell lysate per well onto an SDS-PAGE gel. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat dry milk in TBST for 1 hour at room temperature. The membrane was probed with a 14-3-3 zeta polyclonal antibody (Product # PA5-27317) at a dilution of 1:1000 overnight at 4°C, washed in TBST, and probed with an HRP-conjugated goat anti-rabbit IgG secondary antibody at a dilution of 1:40,000 for 1 hour at room temperature. Detection was performed using ECL substrate. Data courtesy of the Innovators Program.

Experimental details: Knockdown of 14-3-3 zeta was achieved by transfecting MCF7 with YWHAZ specific siRNAs (Silencer® select Product # s14972). Western blot analysis (Fig. a) was performed using whole cell extracts from the YWHAZ knockdown cells (Lane 3), non-specific scrambled siRNA transfected cells (Lane 2) and untransfected cells (Lane 1). The blot was probed with 14-3-3 zeta Polyclonal Antibody (Product # PA5-27317, 1:2000 dilution) and Goat anti-Rabbit IgG (H+L), Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036, 0.25µg/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 YWHAZ.

Experimental details: Western blot was performed using Anti-14-3-3 zeta Polyclonal Antibody (Product # PA5-27317) and a 27 kDa band corresponding to YWHAZ was observed across all the cell lines and tissues tested. Whole cell extracts (25 µg lysate) of MCF7 (Lane 1), HeLa (Lane 2), PC-12 (Lane 3), NIH/3T3 (Lane 4) and tissue extracts of Mouse Brain (Lane 5) were electrophoresed using Novex® NuPAGE® 12 % Bis-Tris gel (Product # NP0342BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (1:2000 dilution) and detected by chemiluminescence with Goat anti-Rabbit IgG (H+L), Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036, 1:4000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

Experimental details: Immunofluorescent analysis of 14-3-3 zeta (green) HEK293T cells. Cells fixed with 4% formaldehyde fixed were permeabilized and blocked with 1X PBS containing 5% BSA and 0.3% Triton X-100 for 1 hour at room temperature. Cells were probed with a 14-3-3 zeta ppolyclonal antibody (Product # PA5-27317) at a dilution of 1:100 overnight at 4°C in 1X PBS containing 1% BSA and 0.3% Triton X-100, washed with 1X PBS, and incubated with fluorophore-conjugated goat anti-rabbit IgG secondary antibody at a dilution of 1:200 for 1 hour at room temperature. Nuclei (blue) were stained with DAPI. Images were taken on a Leica DM1000 microscope at 40X magnification. Data courtesy of the Innovators Program.

Experimental details: Immunofluorescence analysis of YWHAZ was performed using 70% confluent log phase MCF7 cells. The cells were fixed with 4% Paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 2% BSA for 10 minutes at room temperature. The cells were labeled with 14-3-3 zeta Polyclonal Antibody (Product # PA5-27317) at 1:200 dilution in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Goat anti-Rabbit IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32731, 1:2000 dilution) for 45 minutes at room temperature (Panel a: Green). Nuclei (Panel b: Blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). F-actin (Panel c: Red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing Cytoplasmic and endoplasmic reticulum like localization of YWHAZ. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

Experimental details: Immunoprecipitation of 14-3-3 zeta was performed on THP-1 cells. Antigen-antibody complexes were formed by incubating 400ug of THP-1 whole cell lysate (in 400ul volume) with 5ul of a 14-3-3 zeta polyclonal antibody (Product # PA5-27317) overnight at 4¼C. The immune complexes were captured on 30ul of protein G agarose, washed extensively, and eluted with 6X non-reducing Laemmli buffer. Samples were resolved on a 10% SDS-PAGE, transferred to a PVDF membrane, and blocked with 5% milk in TBST for 1 hour at room temperature. The membrane was probed with a 14-3-3 zeta polyclonal antibody (Product # PA5-27317) at a dilution of 1:2000 overnight at 4¡C, washed in TBST, and probed with an HRP-conjugated goat anti-rabbit IgG secondary antibody at a dilution of 1:40,000 for 1 hour at room temperature.
