General description

Cytokeratins 8 &18 (CK 8 & 18) are major components of the intermediate filaments in the thyroid, liver, and most simple epithelia (e.g. breast, gastrointestinal and respiratory tracts). Anti-CK 8 & 18 is found to stain most adenocarcinomas and squamous cell carcinomas. CK8 & 18 are frequently used as the epithelial markers for identifying Paget cells, metastatic gastric, and colorectal carcinomas.

M Sasaki et al.
Histopathology, 32(3), 199-208 (1998-05-06)
Recent reports suggest that genetic examination of K-ras or p53 mutation is more sensitive for the detection of occult lymph node metastasis in colorectal carcinomas than conventional examination by haematoxylin and eosin (H & E) staining or immunohistochemistry for gene
B Angus et al.
The Journal of pathology, 153(4), 377-384 (1987-12-01)
Production of a new monoclonal antibody designated NCL-5D3 is described. The antibody recognizes several low molecular weight cytokeratins, in particular cytokeratin Moll number 8 as determined by immunoblotting studies, and is highly effective for immunocytochemistry using routinely processed paraffin-embedded material.

Keratin protein immunohistochemistry is a powerful diagnostic tool whose role has already been firmly established in many surgical pathology laboratories. Recent studies of the biology of keratin proteins have defined the heterogeneity of keratin protein expression among various epithelial tissues
