Figure 3From: Evaluation of gene amplification and protein expression of HER-2/neu in esophageal squamous cell carcinoma using Fluorescence in situ Hybridization (FISH) and immunohistochemistry Analysis of HER-2/neu gene amplification in 47 cases of ESCC. (a) Samples with no amplification; (b) case considered amplified. In detail, nucleus shows ratio ≥ 2 and (c) gene amplification showing cluster pattern. 1000×.Back to article page
