From: EBV persistence in gastric cancer cases conventionally classified as EBER-ISH negative
Sensitive in situ detection of EBV by RNAscope assay and immunofluorescence: Single red dot, produced by EBNA1 mRNA probes, were detected in EBER-ISH negative cases (A–B: GCLS; C: ADK). Double staining pan-keratin (IF, green) and EBNA1 (RNAScope, red) showed the presence of EBV traces in GC neoplastic cells (inset). Original magnification: 40X
