General Description of Cytokeratin.
This MAb recognizes basic (Type II or HMW) cytokeratins, which include 67kDa (CK1); 64kDa (CK3); 59kDa (CK4); 58kDa (CK5); 56kDa (CK6); 52kDa (CK8). Twenty human keratins are resolved with two-dimensional gel electrophoresis into acidic (pI 6.0) subfamilies. The acidic keratins have molecular weights (MW) of 56.5, 55, 51, 50, 50 , 48, 46, 45,, 40kDa. MAb AE3 recognizes the 65-67, 64, 59, 58, 56,, 52kDa keratins of basic subfamily. Many studies have shown the usefulness of keratins as markers in cancer research, tumor diagnosis. AE1/AE3 is a broad spectrum anti pan-keratin antibody cocktail, which differentiates epithelial tumors from non-epithelial tumors e.g. squamous vs. adenocarcinoma of the lung, liver carcinoma, breast cancer,, esophageal cancer.

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
