Anti-Cytokeratin (CAM 5.2)

Anti-Cytokeratin (CAM 5.2) reagent has a primary reactivity with human keratin proteins that correspond to Moll’s peptides #7 and #8, Mr 48 and 52 kilodaltons (kd), respectively.

Cytokeratin 7 and 8 are present on secretory epithelia of normal human tissue but not on
stratified squamous epithelium.

Anti-Cytokeratin (CAM 5.2) stains most epithelial-derived tissue, including liver, renal tubular epithelium, and hepatocellular and renal cell carcinomas.

Anti-Cytokeratin (CAM 5.2) might not react with some squamous cell carcinomas.
