Cytokeratin 20 (Autostainer/Autostainer Plus)

Reacts with the 46 kDa protein corresponding to cytokeratin 20. The antibody is a useful aid for classification of adenocarcinomas of the colon, mucinous ovarian tumors, transitional-cell and Merkel-cell carcinomas, adenocarcinomas of the stomach, bile system and pancreas. Results also aid in the classification of most squamous cell carcinomas and most adenocarcinomas from other sites (breast, endometrium, lung, prostate), non-mucinous tumors of the ovary, and small-cell lung carcinomas as these may be negative.
