Experimental details: Knockdown of CDK4 was achieved by transfecting A-431 cells with CDK4 specific validated siRNA (Silencer® select Product # s2823). Western blot analysis (Fig. a) was performed using whole cell extracts from the CDK4 knockdown cells (lane 3), non-specific scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blots were probed with Anti-CDK4 Polyclonal Antibody (Product # PA5-27827, 1:500 dilution) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/mL, 1:4000 dilution). 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 CDK4.

Experimental details: Western blot analysis was performed on whole cell extracts (30 µg lysate) of A-431 (Lane 1), U-87 MG (Lane 2), K-562 (Lane 3), HeLa (Lane 4) and A549 (Lane 5). The blot was probed with Anti-CDK4 Polyclonal Antibody (Product # PA5-27827, 1:500 dilution) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/mL, 1:4000 dilution). A ~35 kDa band corresponding to CDK4 was observed across the cell lines tested. A non-specific band was also observed at around 55 kDa.
