The Human EGFR Pathway qBiomarker Somatic Mutation PCR Array profiled 85 mutations (x axis) in 4 FFPE cell line samples, a wild-type FFPE placenta sample control, and 9 lung adenocarcinoma FFPE tissue samples of primarily (8 out of the 9 samples) Caucasian origin with mixed gender and smoking status (samples along y axis). The array detected BRAF and KRAS mutations in the FFPE MDAMB- 231 cell line (shown as peaks), which were independently confirmed using the QIAGEN KRAS PCR Kit and Pyrosequencing. One KRAS somatic mutation and one EGFR somatic mutation were also detected in 2 FFPE lung adenocarcinoma samples.
