Western blot analysis was performed on whole cell extracts (30 ug lysate) of K562 (Lane 1), COS-7 (Lane 2), HEK-293 (Lane 3), HeLa (Lane 4), and PC-3 (Lane 5). The blots were probed with Anti-Cdk4 Mouse Monoclonal Antibody (Product# MA512984, 1-2 ug/mL) and detected by chemiluminescence using Goat anti-Mouse IgG (H+L) Secondary Antibody, HRP conjugate (Product # 626520, 1:4000 dilution). A 33 kDa corresponding to Cdk4 was observed across cell lines tested. The 17 kDa isoform was observed across cell line except COS-7. Additionally 60 kDa band was seen in COS-7, HeLa and PC-3. 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 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 Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).
