Epidermal growth factor receptor (EGFR) is one of the most frequently amplified, mutated and/or overexpressed genes in human malignancies. Inactivation of EGFR kinase with tyrosine kinase inhibitors (TKIs), such as gefitinib (Iressa) and erlotinib (Tarceva), suppresses signal transduction pathways which control tumor cell growth, proliferation, and resistance to apoptosis. TKIs therapy has shown a significant symptom benefit and prolongs survival on the treatment of Non-Small Cell Lung Cancer (NSCLC) patients with somatic mutations in the EGFR gene. Therefore, detection of the somatic mutations in the EGFR gene may predict a more accurate response of the cancer patients to TKIs therapy.​

Medaysis Ultra-Sensitive EGFR Mutation Detection Kit is a highly specific and sensitive PCR technique that is able to detect common somatic mutations in the EGFR gene. Used with Sanger sequencing, it can detect less than 1% (as little as 20 ng to 100 ng of) mutant genes mixed with the wild-type.  It is designed to amplify CFDNA EGFR gene from formalin-fixed paraffin-embedded (FFPE) tissues, fresh or frozen tissues, fine needle biopsies (FNA), pleural effusion specimens, or and plasma samples. 

The feature of Medaysis mutation detection kit:
1. Detect known and unknown mutation in target Exons
2. Highly specific and sensitive mutation enrich technology
3. Open system and easy to be done
4. Minimal sample size
5. No microdissection required
