Figure 2.
Fluorescence in situ hybridisation targeting ERBB2 in gastric carcinoma specimens (original magnification, × 1000). Red labelled probes target the ERBB2, green labelled probes target chromosome 17 centromere, and nuclei (blue) are stained with DAPI. (A) intestinal type carcinoma (score 0 by IHC) with no ERBB2 amplification; (B) intestinal type carcinoma (score 2+ by IHC) showing ERBB2 amplification; (C) intestinal type carcinoma (score 1+ by IHC) showing ERBB2 amplification.
