Zeta Cytokeratin-7 (CK7) Antibody. Zeta’s rabbit recombinant monoclonal IVD antibody for IHC recognizes Cytokeratin-7 (CK7), an intermediate filament protein (IFP) of 55kDa. The Cytokeratin-7 antibody is highly specific to cytokeratin-7 and shows no cross-reaction with other IFPs. Cytokeratin-7 is a basic cytokeratin, which is found in most glandular and transitional epithelia but not in the stratified squamous epithelia. Cytokeratin-7 is expressed in the epithelial cells of ovary, lung, and breast but not of colon, prostate, or gastrointestinal tract. Zeta’s antibody to Cytokeratin-7 (CK7) is highly useful in distinguishing ovarian carcinomas (Cytokeratin-7+) from colon carcinomas (Cytokeratin-7-).
