Experimental details: Knockdown of PRMT3 was achieved by transfecting HeLa cells with PRMT3 specific validated siRNA (Silencer® select Product # s19870). Western blot analysis Fig (a) was performed using whole cell lysates from the PRMT3 knock down cells (lane 3), non-specific scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blots were probed with Anti-PRMT3 Mouse Monoclonal Antibody (Product # 730020, 0.5-1 µg/mL) and Goat anti-Mouse IgG (H+L) Secondary Antibody, HRP conjugate (Product # 62-6520, 1:4000 dilution). Densitometric analysis of this western blot is shown in histogram (Fig b). Loss of signal upon siRNA mediated knock down confirms that antibody is specific to PRMT3.

Experimental details: Western blot analysis was performed on whole cell extracts (30 µg lysate) of T47D (Lane 1), A549 (Lane 2), U2OS (Lane 3), K562 (Lane 4), HeLa (Lane 5), Raji (lane 6), HEK-MSR (lane 7), MCF7 (lane 8), MDA-MB-231 (lane 9), LNCaP (lane 10) and Hep G2 (lane 11). The blots were probed with Anti-PRMT3 Mouse Monoclonal Antibody (Product # 730020, 0.5-1 µg/mL) and detected by chemiluminescence using Goat anti-Mouse IgG (H+L) Secondary Antibody, HRP conjugate (Product # 62-6520, 1:4000 dilution). A 59 kDa band corresponding to PRMT3 was observed across cell lines tested expect Raji and HEK-MSR. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 12 % Bis-Tris gel (Product # NP0342BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a 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).

Experimental details: Immunofluorescence analysis of PRMT3 was done on 70% confluent log phase A549 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with PRMT3 Mouse Monoclonal Antibody (Product # 730020) at 2 µg/mL in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A28175) at a dilution of 1:2000 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 Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d is a merged image showing punctuated cytoplasmic localization. Panel e is a no primary antibody control. The images were captured at 60X magnification.

Experimental details: Immunohistochemistry analysis of PRMT3 showing staining in the cytoplasm of paraffin-embedded human breast carcinoma (right) compared to a negative control without primary antibody (left). To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with a Anti- PRMT3 Monoclonal Antibody (Product # 730020) diluted in 3% BSA-PBS at a dilution of 1:20 overnight at 4°C in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

Experimental details: Flow cytometry analysis of PRMT3 was done on MCF7 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 PRMT3 Mouse Monoclonal Antibody (730020, red histogram) or with mouse isotype control (yellow 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 Rabbit Anti-Mouse Secondary Antibody (A11059) 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.

Experimental details: Immunoprecipitation analysis of Anti-PRMT3 Recombinant Mouse Monoclonal Antibody (Product # 730020). Immunoprecipitation analysis was performed on HEK293 cells over expressing flag tagged PRMT3 protein. Western blot using anti-flag antibody was performed on the raw lysate (lane 1), and samples immunoprecipitated with Anti-PRMT3 Recombinant Mouse Monoclonal Antibody (lane 2).
