Anti-Keratin 18 (Cytokeratin 18, Keratin, Type I Cytoskeletal 18)

Reacts with a wide variety of simple epithelia. It does not react with stratified squamous epithelia. It reacts with epithelial tumors of the gastrointestinal tract, lung, breast, pancreas, ovary, and thyroid. Cytokeratin 18, which belongs to the type A (acidic) subfamily of low molecular weight keratins, exists in combination with cytokeratin 8. It is reported that tissues from gastrointestinal tract are positive for both cytokeratin 8 and 18 but do not contain cytokeratin 14. Tissues from gastrointestinal tract, respiratory tract and urogenital tract, as well as endocrine and exocrine tissues and mesothelial cells are positive for cytokeratin 18. Applications: Suitable for use in Flow Cytometry, Western Blot, Immunofluorescence and Immunohistochemistry. Other applications not tested. Recommended Dilutions: Western Blot: 0.5-1ug/ml, Flow Cytometry: 0.5-1ug/10e6 cells, Immunofluorescence: 1-2ug/ml, Immunohistochemistry (FFPE): 0.5-1ug/ml for 30 min at RT. Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0 for 10-20 minutes followed by cooling at RT for 20 minutes. , Optimal dilutions to be determined by the researcher.
