- Western blot analysis was performed on whole cell extracts (30 µglysate) of HeLa (Lane 1), HeLa treated with IFN gamma (100 ng/mL IFN gamma for 72h) (Lane 2), U-937 (Lane 3), Raji (Lane 4) and Ramos (Lane 5).The blots were probed with PSMB8 Rabbit polyclonal Antibody (Product # PA1-972, 2 µg/mL) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.4 µg/mL, 1:2500 dilution). A 20 kDa band corresponding to PSMB9 was observed across the cell line tested and was enhanced upon IFN gamma treatment in HeLa cell line. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 4-12 % Bis-Tris gel (Product # NP0322BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then 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).

- Immunofluorescent analysis of Proteasome 20S LMP7 (green) in HeLa cells. The cells were fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0.1% Triton X-100 in TBS for 10 minutes, and blocked with 3% Blocker BSA (Product # 37525) in PBS for 15 minutes at room temperature. Cells were stained with or without Proteasome 20S LMP7 rabbit polyclonal antibody (Product # PA1-972), at a concentration of 5 µg/mL for 1 hour at room temperature, and then incubated with a Alexa Fluor® 488 Superclonal goat anti-rabbit IgG secondary antibody (Product # A27034) at a dilution of 1:1000 for 1 hour s at room temperature (both panels, green). Nuclei (both panels, blue) were stained with Hoechst 33342 dye (Product # 62249). Images were taken on a Thermo Scientific ToxInsight at 20X magnification.

- Flow cytometry analysis of PSMB8 was done on SH-SY5Y 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 PSMB8 Rabbit Polyclonal Antibody (PA1972, red histogram) or with rabbit isotype control (pink 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 Goat Anti-Rabbit Secondary Antibody (A11008) 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..
