The Cytokeratin 7 & 8 antibody has a primary reactivity with human cytokeratin proteins that correspond to Moll's peptide 7 (cytokeratin 7) and Moll's peptide 8 (cytokeratin 8).^1-4 These antigens are present on secretory epithelia of normal human tissue, but not on stratified squamous epithelium.¹ Its antibody stains most epithelial-derived tissue, including liver, renal tubular epithelium, and hepatocellular and renal cell carcinomas. It may not react with some squamous cell carcinomas. ^{2, 5, 6}

• Control: Adenocarcinomas, pancreas, prostate, salivary gland
• Dilution Range: 1:400-1:800 for immunohistochemical staining
