- Knockdown of Cohesin subunit SA-1 was achieved by transfecting MCF 10A with Cohesin subunit SA-1 specific siRNAs (Silencer® select Product # s20075, s20076). Western blot analysis (Fig. a) was performed using Whole cell extracts from the Cohesin subunit SA-1 knockdown cells (lane 3), non-targeting scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blot was probed with STAG1 Polyclonal Antibody (Product # PA5-57115, 1:3000 ) and Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036, 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 Cohesin subunit SA-1.

- Western blot was performed using Anti-STAG1 Polyclonal Antibody (Product # PA5-57115) and a 150kDa band corresponding to Cohesin subunit SA-1 was observed. Whole cell extracts (30 µg lysate) of HeLa (Lane 1), Jurkat (Lane 2), MCF7 (Lane 3) and PC-12 (Lane 4) were electrophoresed using NuPAGE™ 4-12% Bis-Tris Protein Gel (Product # NP0322BOX). 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 (1:3000) and detected by chemiluminescence with Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036,1:20,000 using the iBright™ FL1500 Imaging System (Product # A44115). Chemiluminescent detection was performed using SuperSignal™ West Pico PLUS Chemiluminescent Substrate (Product # 34580).

- Immunofluorescence analysis of Cohesin subunit SA-1 was performed using 70% confluent log phase MCF 10A 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 1 hour at room temperature. The cells were labeled with STAG1 Polyclonal Antibody (Product # PA5-57115) at 0.5 ug/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 nuclear localization. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.
