- Western blot analysis was performed on Whole cell extracts (30 µg lysate) of Caco-2 (Lane 1), Caco-2 treated with EGF (100 ng/mL for 20 min) (Lane 2), MCF7 (Lane 3), MCF7 treated with EGF (100 ng/mL for 20 min) (Lane 4), HeLa (Lane 5) and HeLa treated with EGF (100 ng/mL for 20 min) (Lane 6). The blots were probed with Anti-Phospho-Cytokeratin 8 (Ser432) Rabbit Monoclonal Antibody (Product # 702176, 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 59 kDa band corresponding to Phospho-Cytokeratin 8 (Ser432) was observed across the cell lines tested. 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).

- For immunofluorescence analysis CACO-2 cells were fixed and permeabilized for detection of endogenous Phospho-Cytokeratin 8 (Ser432) using Anti-Phospho-Cytokeratin 8 (Ser432) Recombinant Rabbit Monoclonal Antibody (Product # 702176, 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 Rhodamine Phalloidin (Product # R415, 1:300) was used for cytoskeletal F-actin (red) staining. Detection and localization of Phospho-Cytokeratin 8 (Ser432) (green) in the cytoskeleton can be clearly observed in cells treated with EGF (100 ng/mL, 20 min) as compared to untreated cells. Antibody specificity was demonstrated by competition with the Cytokeratin 8 (Ser432) phospho peptide, which results in loss of signal. No competition was observed with the non-phospho peptide. The images were captured at 60X magnification.
