Isotype
Mouse IgG2a
Specificity
The mouse monoclonal antibody A53-B/A2 recognizes the rod domain of cytokeratin 19 (40 kDa), an intracellular antigen constituting intermmediate cytoskeleton filaments. Cytokeratin 19 is not expressed in hepatocytes; it is often co-expressed with cytokeratin 7.
Application details
Flow cytometry: Recommended dilution: 1-5 μg/ml.
Western blotting: Recommended dilution: 1-2 μg/ml.
Reactivity
Human
Immunogen
MCF-7 human breast adenocarcinoma cell line
Concentration

Antigen description
Cytokeratins are a subfamily of intermediate filaments and characterized by remarkable biochemical diversity. They are represented in epithelial tissues by at least 20 different polypeptides, molecular weight between 40 kDa and 68 kDa. The individual cytokeratin polypeptides are designated 1 to 20 and divided into the type I (acidic cytokeratins 9-20) and type II (basic to neutral cytokeratins 1-8) families.

1B-120_WB
Western blotting analysis of human cytokeratin 19 using mouse monoclonal antibody A53-B/A2 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 biotinylated mouse anti-cytokeratin 19 monoclonal antibody followed by IRDye800-conjugated streptavidin. Cytokeratin 19 was detected at approximately 41 kDa.
