It recognizes polypeptides of 58kDa, 56kDa, and 45kDa, identified as cytokeratin 5, 6, and 18 respectively. It shows no reaction with keratin 1, 8, or 19. This MAb shows a broad pattern of reactivity with epithelial tissues, from simple glandular epithelia to stratified squamous epithelia. Epithelial cells are labeled whether they are ectodermal, mesodermal, or endodermal in origin. This MAb is useful in detecting cells of epithelial origin in mixed tumors, in effusions, in bone marrow samples, or in tissue culture cells.
Optimal dilution of the Cytokeratin 5/6/18 antibody should be determined by the researcher.
The detergent-insoluble fraction of psoriatic human epidermis was used as the immunogen for the Cytokeratin 5/6/18 antibody.
Store the Cytokeratin 5/6/18 antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
