From: Characteristics of epstein barr virus variants associated with gastric carcinoma in Southern Tunisia
Detection of Epstein-Barr virus encoded small RNAs (EBERs) by in-situ hybridization in gastric carcinoma tissues. A: H&E staining. B: Intense EBER positive staining (immuno-score 3+) in the nuclei of tumor cells (original magnification × 40). C: Moderate EBER positive staining (immuno-score 2+) in the nuclei of tumor cells (original magnification × 40). D: Weak EBER positive staining (immuno-score 1+) in the nuclei of tumor cells (original magnification × 40). E: Positive control represented by a known EBER-positive NPC tissues (original magnification × 40). F: Gastric carcinoma tissues negative for EBER (original magnification × 10).
