General Description of Cytokeratin.
This antibody recognizes CK1, CK5, CK10, CK14. In normal epithelia, it stains stratified epithelia, myoepithelial cells, basal cells in the prostate gland, bronchi. This MAb shows no reactivity with hepatocytes, pancreatic acinar cells, proximal renal tubules, or endometrial glands; there is no reactivity with cells derived from simple epithelia. Mesenchymal tumors, lymphomas, melanomas, neural tumors,, neuroendocrine tumors are negative with this antibody. It stains myoepithelial cells, has been shown to be useful in distinguishing prostate adenocarcinoma from benign prostate. This antibody has also been useful in separating benign from malignant intraductal breast proliferations.

Cytokeratin Previously Observed Antibody Staining Patterns

Observed Antibody Staining Data By Tissue Type:

Variations in Cytokeratin antibody staining intensity in immunohistochemistry on tissue sections are present across different anatomical locations. Low, but measureable presence of Cytokeratin could be seen in. We were unable to detect Cytokeratin in other tissues. Disease states, inflammation, and other physiological changes can have a substantial impact on antibody staining patterns. These measurements were all taken in tissues deemed normal or from patients without known disease.

Observed Antibody Staining Data By Tissue Disease Status:

Tissues from cancer patients, for instance, have their own distinct pattern of Cytokeratin expression as measured by anti-Cytokeratin antibody immunohistochemical staining. The average level of expression by tumor is summarized in the table below. The variability row represents patient to patient variability in IHC staining.

Sample Type breast cancer carcinoid cervical cancer colorectal cancer endometrial cancer glioma head and neck cancer liver cancer lung cancer lymphoma melanoma ovarian cancer pancreatic cancer prostate cancer renal cancer skin cancer stomach cancer testicular cancer thyroid cancer urothelial cancer
