NRAS is a member of the RAS oncogene family and plays a role in the pathogensis in various cancers. Activating RAS mutations including KRAS, NRAS and HRAS have been found in 15-25% of human tumors and mainly in condons 12, 13, 59, 61. NRAS mutation accounts for 15% of all RAS mutation and indicates relative resistance to anti-EGFR therapy. Medaysis NRAS Mutation Detection Kit includes the primer set used to amplify NRAS gene and the DNA quality control primers to assure concordance of the test results.​

Medaysis Ultra-Sensitive NRAS Mutation Detection Kit is a highly specific and sensitive PCR technique that is able to detect common somatic mutations in the NRAS 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 NRAS gene from formalin-fixed paraffin-embedded (FFPE) tissues, fresh or frozen tissues, fine needle biopsies (FNA), pleural effusion specimens, or and plasma samples.  

Features 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
