Figure 1From: Systematic analysis of human oncogenic viruses in colon cancer revealed EBV latency in lymphoid infiltratesEBV latency is restricted to the inflammatory infiltrate in colon cancer. Tissue RNA in situ hybridization using EBER 1ā2 PNA probes to detect EBV latency (Dako, Denmark). A blue nuclear staining indicates a positive reaction. Epithelial and cancer cells are negative, whereas occasionally positivity of non-neoplastic lymphoid cells may be extensive (reaching 20%).Back to article page
