Associated Diseases (KEGG IDs)White sponge nevus 2 (WSN2) [MIM:615785]: A rare disorder characterized by the presence of soft, white, and spongy plaques in the oral mucosa. The characteristic histopathologic features are epithelial thickening, parakeratosis, and vacuolization of the suprabasal layer of oral epithelial keratinocytes. Less frequently the mucous membranes of the nose, esophagus, genitalia and rectum are involved. {ECO:0000269|PubMed:10561721, ECO:0000269|PubMed:11379896, ECO:0000269|PubMed:14600690, ECO:0000269|PubMed:7493031}. The disease is caused by mutations affecting the gene represented in this entry.
General Description of Cytokeratin 13 .
This antibody is specific to 54 kDa protein. Cytokeratin 13 belongs to the type A (acidic) subfamily of low molecular weight cytokeratins and exists in combination with cytokeratin 4. Cytokeratin 13 is expressed in squamous, non-keratinized epithelium, transitional epithelium and myoepithelium. This antibody is useful for the identification of carcinomas of trachea, sweat glands, bladder, ectocervix, tongue, esophagus, anal canal and the basal layer of keratinized epidermis.

Cytokeratin 13 Information for Pathologists


Molecular weight is 53 kDa. Pairs with CK4. Marker of mature but non-keratinized squamous epithelium. Downregulated in squamous cell carcinoma of head and neck (Oral Oncol 2005;41:183) and other sites (Virchows Arch A Pathol Anat Histopathol 1991;418:249). Sensitive marker for retinoid bioactivity in skin warts of renal transplant recipients (Arch Dermatol 2002;138:61).

Common Uses By Pathologists:

No significant clinical use by pathologists. Positive staining - normal Suprabasal layers of non-cornified stratified epithelium, including squamous (non-keratinized) epithelia of cervix, esophagus, larynx, oral cavity, tonsils, urothelium, and respiratory-type epithelium. May be filled with mucoid material or foamy macrophages. Positive staining - disease

Limitations and Warranty

This antibody is manufactured in accordance with clinical good manufacturing practices in an ISO13485:2016 certified production facility. It is intended for multiple uses including in vitro diagnostic use and research use only applications. Please see vial label for expiration date. We strive to always deliver antibodies with a shelf life of at least two years.
