Western blot analysis was performed on whole cell extracts (30 µglysate) of MCF7 (Lane 1), PC-3 (Lane 2), Hep G2 (Lane 3), SK-OV-3 (Lane 4), HeLa (Lane 5), COS-7 (Lane 6), Jurkat (Lane 7), A-431 (Lane 8) and tissue extracts (30 µglysate) of Mouse Testis (Lane 9) and Rat Testis (Lane 10). The blot was probed with Anti-PSMD1 Rabbit Polyclonal Antibody (Product # PA1-973, 1 µg/mL) and detected by chemiluminescence using Goat anti-Rabbit IgG (Heavy Chain) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.4 µg/mL, 1:2500 dilution). A 106 kDa band corresponding to PSMD1 was observed across the cell lines and tissues tested. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 10 % Bis-Tris gel (Product # NP0302BOX), 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 overnight wet transfer system. 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).
