Comparison of COBAS 4800 KRAS, TaqMan PCR and high resolution melting PCR assays for the detection of KRAS somatic mutations in formalin-fixed paraffin embedded colorectal carcinomas.

Abstract excerpt

Many studies documented the influence of KRAS mutation status on the response of patients with metastatic colorectal cancer (mCRC) to anti-EGFR monoclonal antibodies. The COBAS 4800 KRAS is an assay using real time PCR and TaqMelt technology, CE-IVD validated, for the detection of 19 KRAS somatic mutations in exons 2 and 3. We compared COBAS with previously validated PCR TaqMan and High Resolution Melting (HRM)...
