This antibody recognizes cytokeratin 10 (56.5kDa) and cytokeratin 13 (53kDa) in western blotting. It recognizes only cytokeratin 13 in formalin-fixed, paraffin-embedded tissue sections. It does not react with cytokeratin 10 positive, cytokeratin 13 negative epithelia such as epidermis. However, on frozen sections this mAb serves as differentiation-related marker of all stratified epithelia; it stains all suprabasal cells in both cornifying and non-cornifying stratified epithelia and more differentiated cells of squamous carcinomas.

Optimal dilution of the Cytokeratin 10/13 antibody should be determined by the researcher.

1. Staining of formalin-fixed tissues requires boiling tissue sections in pH 9 10mM Tris with 1mM EDTA for 10-20 min followed by cooling at RT for 20 min.2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.

A cytoskeletal preparation extracted from human ectocervical epithelium was used as the immunogen for the Cytokeratin 10/13 antibody.

Store the Cytokeratin 10/13 antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
