Figure 1From: Epidermal growth factor receptor in breast carcinoma: association between gene copy number and mutationsAnalysis of EGFR gene amplification and mutations based on FISH and RT-PCR analysis. A: FISH positive (amplification), B: FISH negative (low trisomy), C: mutation positive (the left ascending curve represents the positive control, the right ascending curve represents the exon 21 L858R mutation), D: mutation negative (the ascending curve represents the positive control).Back to article page
