Immunohistochemistry staining of human prostate (paraffin sections) using anti-cytokeratin 19 (A53-B/A2).

Immunohistochemistry staining (paraffin sections) of cytokeratin 19 in human liver using mouse monoclonal antibody A53-B/A2 (orb43633, diluted 1:100), detected with GAM IgG-Alexa Fluor®488 (diluted 1:200; green), cell nuclei stained with PI (1 µg/ml; orange).

Western blotting analysis of human cytokeratin 19 using mouse monoclonal antibody A53-B/A2 on lysates of HT-29 cell line and Jurkat 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 19 monoclonal antibody A53-B/A2 followed by IRDye800-conjugated anti-mouse IgG1 secondary antibody. A specific band was detected for cytokeratin 19 at approximately 40 kDa.
