- Knockdown of TOMM20 was achieved by transfecting HeLa with TOMM20 specific siRNAs (Silencer® select Product # s18949, s18948). Western blot analysis (Fig. a) was performed using Membrane enriched extracts from the TOMM20 knockdown cells (lane 3), non-targeting scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blot was probed with TOMM20 Polyclonal Antibody (Product # PA5-52843, 0.1 µg/mL) and Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036, 1:4000 dilution). Densitometric analysis of this western blot is shown in histogram (Fig. b). Decrease in signal upon siRNA mediated knockdown confirms that antibody is specific to TOMM20.

- Western blot was performed using Anti-TOMM20 Polyclonal Antibody (Product # PA5-52843) and a 15 kDa band corresponding to TOMM20 was observed across cell lines and tissue extracts tested. Membrane enriched extracts (30 µg lysate) of HeLa (Lane 1), Hep G2 (Lane 2), MCF7 (Lane 3), HL-60 (Lane 4), NIH/3T3 (Lane 5), PC-12 (Lane 6) and tissue extracts of Mouse Brain (Lane 7) and Rat Brain (Lane 8) were electrophoresed using NuPAGE™ 12% Bis-Tris Protein 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 (0.1 µg/mL) 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).

- Immunofluorescence analysis of TOMM20 was performed using 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 45 minutes at room temperature. The cells were labeled with TOMM20 Polyclonal Antibody (Product # PA5-52843) at 2 µg/mL in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Donkey anti-Rabbit IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32790), (1:2000), for 45 minutes at room temperature (Panel a: Green). Nuclei (Panel b:Blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). F-actin (Panel c: Red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing cytoplasmic(mitochondrial like pattern) localization. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.
