Anti-Cytokeratin 18 Purified

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. Cytokeratin 18 belongs to type I family (acidic cytokeratins) .

Specificity

The mouse monoclonal antibody DA-7 reacts with cytokeratin 18 (45 kDa) . Cytokeratins are members of intermediate filaments subfamily of intracellular proteins represented in epithelial tissues.

Applications Notes

Western blotting: Recommended dilution: 1-2 μg/ml.Immunohistochemistry (paraffin sections) : Recommended dilution: 10 μg/ml; positive tissue: colon, skin. Immunocytochemistry: Positive control: MCF-7 human breast adenocarcinoma cell line, HeLa human cervix carcinoma cell line.ELISA: Positive control: MCF-7 human breast adenocarcinoma cell line; the antibody DA-7 has been tested as the detection antibody in a sandwich ELISA for analysis of Cytokeratin 18 in combination with the antibody C-04 (cat. no. 11-106-C100) .
