The AmoyDx EGFR Mutations Detection Kit is a sensitive and selective assay for the detection of the most informative somatic mutations in the epidermal growth factor receptor (EGFR) gene. It is used clinically in China to select NSCLC patients who are most likely to respond to Iressa (Gefitinib) or Tarceva (Erlotinib). AmoyDx works closely with AstraZeneca in China to promote the use of molecular diagnostic tests for patient stratification. The EGFR assay tests for a total of 29 mutations in eight PCR tubes, including both activating and resistance mutations. The EGFR mutation kit enables detection of the following mutations: T790M, L858R, L861Q, S768I, G719S,G719A and G719C, 3 insertions in exon 20 (detects the presence of any of 3 insertions but does not distinguish between them), 19 deletions in exon 19 (detects the presence of any of the 19 deletions but does not distinguish between them).
