Additional info: Cytokeratins are a subfamily of intermediate filaments and are 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. Cytokeratins 10 and 13 both belong to type I family (acidic cytokeratins).SpecificityThe 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 detailsImmunohistochemistry (paraffin sections): Standard ABC technique (DAB+), recommended dilution: 10 μg/ml (1:100), positive tissue: tonsil. Pretreatment: 0.1% pepsin in 0.1 M HCl for 30 min at room temperature or Target Retrieval Solution - High pH. The antibody DE-K13 reacts exclusively with Cytokeratin 13.
Immunohistochemistry (frozen sections): Use at an assay dependent dilution.
Western blotting: recommended dilution: 1-3 μg/ml.
