Experimental details

Western blot analysis was performed on whole cell extracts (30 µg lysate) of COLO 205 (Lane 1, 2 & 3). The blots were probed with Anti-phospho-Rb (Ser807/Ser811) Recombinant Rabbit Monoclonal Antibody (Product # 702097, 1 µg/mL). To confirm the specificity of Phospho-Rb (Ser807/Ser811), competition was performed with the phosphopeptide (10 µg/mL) (Lane 2) and non phosphopeptide (10 µg/mL) (Lane 3). A 110 kDa band corresponding to Phospho-Rb (Ser807/Ser811) was observed as shown. The blots were detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.4 µg/mL, 1:5000 dilution). 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 wet transfer method. 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 Phospho Rb (Ser807/Ser811) using Anti- Phospho Rb (Ser807/Ser811) Recombinant Rabbit Monoclonal Antibody (Product # 702097, 2 µg/mL) and labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034, 1:2000). Panel a) shows representative cells that were stained for detection and localization of Phospho-Rb (Ser807/Ser811) protein (green), Panel b) is stained for nuclei (blue) using SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). Panel c) represents cytoskeletal F-actin staining using Rhodamine Phalloidin (Product # R415, 1:300). Panel d) is a composite image of panels a, b and c clearly demonstrating nuclear localization of Phospho-Rb (Ser807/Ser811). Panel e) shows loss of signal by competition with the Phospho-Rb (Ser807/Ser811) phospho peptide, demonstrating antibody specificity, and panel f) demonstrates no competition with the non-phosphorylated peptide. Panel g) represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.
