- Knockout of RUNX3 was achieved by CRISPR-Cas9 genome editing using LentiArray™ Lentiviral sgRNA (Product # A32042, Assay ID ) and LentiArray Cas9 Lentivirus (Product # A32064). Western blot analysis of RUNX3 was performed by loading 60 µg of HCT 116 wild type (Lane 1), HCT 116 Cas9 (Lane 2) andHCT 116 RUNX3 KO (Lane 3) whole cell extracts. The samples were electrophoresed using NuPAGE™ Novex™ 4-12% Bis-Tris Protein Gel (Product # NP0321BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with Anti-RUNX3 Monoclonal Antibody (2B3) (Product # MA5-17169, 1:500 dilution) and Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:6000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using SuperSignal™ West Dura Extended Duration Substrate (Product # 34076). Loss of signal upon CRISPR mediated knockout (KO) using the LentiArray™ CRISPR product line confirms that antibody is specific to RUNX3. An uncharacterized band observed around ~240 kDa in all the samples.

- Knockdown of RUNX3 was achieved by transfecting HCT 116 with RUNX3 specific siRNAs (Silencer® select Product # S2467, S2468). Western blot analysis (Fig. a) was performed using whole cell extracts from the RUNX3 knockdown cells (lane 3), non-targeting scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blot was probed with RUNX3 Monoclonal Antibody (2B3) (Product # MA5-17169, 1:1500) and Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:20,000). 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 RUNX3.

- Western blot was performed using RUNX3 Monoclonal Antibody (2B3) (Product # MA5-17169) and a ~45 kDa band corresponding to RUNX3 was observed only in Jurkat, SW480, HeLa and Mouse Spleen. Whole cell extracts (30 µg lysate) of Jurkat (Lane 1), SW480 (Lane 2), HeLa (Lane 3), Hep G2 (Lane 4), MCF7 (Lane 5), Mouse Spleen (Lane 6), Rat Spleen (Lane 7) were electrophoresed using NuPAGE™ 4-12% Bis-Tris Protein Gel (Product # NP0322BOX), 12 well. 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 (1:1500) and detected by chemiluminescence with Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:20,000) using the iBright™ FL1500 Imaging System (Product # A44115). Chemiluminescent detection was performed using SuperSignal™ West Pico PLUS Chemiluminescent Substrate (Product # 34580).

- Western blot analysis was performed on modified whole cell extracts (1% SDS) of HCT 116 (Lane 1), SW480 (Lane 2) and Jurkat (Lane 3). The blot was probed with RUNX3 Monoclonal Antibody (2B3) (Product # MA5-17169, 1:1000 dilution) and detected by chemiluminescence using Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A28177, 0.25 µg/mL, 1:4000 dilution). A 45 kDa band corresponding to RUNX3 was observed across the panel.

- Immunofluorescence analysis of RUNX3 was performed using 70% confluent log phase SW480 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 45 minutes at room temperature. The cells were labeled with RUNX3 Monoclonal Antibody (2B3) (Product # MA5-17169) at 1:100 in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Donkey anti-Mouse IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor™ Plus 488 (Product # A32766, 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 nucleus and cytoplasmic localization. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

- Enrichment of endogenous RUNX3 protein at specific gene loci using Anti-RUNX3 Antibody: Chromatin Immunoprecipitation (ChIP) was performed using Anti-RUNX3 Mouse Monoclonal antibody (Product # MA5-17169, 5 µg) on sheared chromatin from 2 million HCT 116 cells using the MAGnify ChIP System (Product # 49-2024). Normal Rabbit IgG was used as a negative IP control. The purified DNA was analyzed by qPCR with PCR primer pairs over the promoters of EZH2, ADAMTS4 and FABP6 (positive) and SAT2 satellite repeats (negative). Data is presented as fold enrichment of the antibody signal versus the negative control IgG using the comparative CT method.
