Separation of MCF-7 cells (red-filled) from Caco-2 cells (black-dashed) in flow cytometry analysis (intracellular staining) of cells stained using anti-cytokeratin 18 (DC-10) purified antibody (concentration in sample 0.6 μg/ml, GAM APC).

Immunocytochemistry staining of cytokeratin 18 in Hep-2 cells using mouse monoclonal antibody DC-10 (orb43750, diluted 1:400), detected with GAM IgG-Alexa Fluor®488 (diluted 1:200; green), cell nuclei stained with PI (1 µg/ml; orange).

Immunohistochemistry staining of human colon (paraffin sections) using anti-cytokeratin 18 (clone DC-10).

Western blotting analysis of human cytokeratin 18 using mouse monoclonal antibody DC-10 on lysates of HT-29 cell line and MOLT-4 cell line (cytokeratin non-expressing cell line; negative control) under non-reducing and reducing conditions. Nitrocellulose membrane was probed with 2 µg/ml of mouse anti-cytokeratin 18 monoclonal antibody followed by IRDye800-conjugated anti-mouse secondary antibody. A specific band was detected for cytokeratin 18 at approximately 46 kDa, and its proteolytic fragment at approximately 25 kDa.
