Newcomer supply cytokeratin 20 (CK20) control slides are for the positive immunohistochemical staining of Cytokeratin 20, expressed in gastric and intestinal epithelium, urothelium and Merkel cells
Staining Results:
CK20 positive expression will stain brown cytoplasmic staining.
Myometrium will stain negative.
Nuclei will stain blue.
These positive control slides are intended to be used to verify histological techniques and reagent reactivity. These slides are to be used for the qualitative purpose of determining positive or negative results, and are not intended to be used for any quantitative purpose.
CK20 has been identified in colon, stomach, pancreas and biliary system adenocarcinomas.
