Experimental details

Western blot analysis was performed on whole cell extracts (30 µg lysate) of COLO 205 (Lane 1) and COLO 205 treated with Nocodazole (3 uM for 24 hrs) (Lane 2). The blots were probed with Anti-Rb (pS788) Recombinant Rabbit Polyclonal Antibody (Product # 711143, 1-2 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 110 kDa band corresponding to Rb (pS788) was observed. To confirm the specificity of Anti-Rb (pS788) Recombinant Rabbit Polyclonal Antibody, competition was performed with the phosphopeptide (10 µg/mL) as shown in the corresponding blot on the right. The phosphopeptide competes with the antibody and prevents it from binding to the target protein. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 4-12% Bis-Tris gel (Product # NP0321BOX), 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® 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).

Experimental details

For immunofluorescence analysis COLO 205 cells were fixed and permeabilized for detection of endogenous RbpS788 using Anti-RbpS788 Recombinant Rabbit Polyclonal Antibody (Product # 711143, 2 µg/mL) and labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034, 1:2000). Nuclei (blue) were stained using SlowFade® Gold Antifade Mountant with DAPI (Product # S36938), and Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300) was used for cytoskeletal F-actin (red) staining. Detection and localization of RbpS788 (green) in the nucleus can be clearly observed in cells treated with Nocodazole (3 uM, 16 h) as compared to untreated cells. Antibody specificity was demonstrated by competition with the RbpS788 peptide, which results in loss of signal. No competition was observed with the non-phospho peptide. The images were captured at 60X magnification.
