A multisite blinded study for the detection of BRAF mutations in formalin-fixed, paraffin-embedded malignant melanoma
Melanoma patients with BRAF mutations respond to treatment with vemurafenib, thus creating a need for accurate testing of BRAF mutation status. We carried out a blinded study to evaluate various BRAF mutation testing methodologies in the clinical setting. Formalin-fixed, paraffin-embedded melanoma samples were macrodissected before screening for mutations using Sanger sequencing, single-strand ...
متن کاملARMS-PCR for detection of BRAF V600E hotspot mutation in comparison with Real-Time PCR-based techniques.
BRAF mutation testing is one of the best examples how modern genetic testing may help to effectively use targeted therapies in cancer patients. Since many different genetic techniques are employed to assess BRAF mutation status with no available comparison of their sensitivity and usefulness for different types of samples, we decided to evaluate our own PCR-based assay employing the amplificati...
متن کاملDMSO Increases Mutation Scanning Detection Sensitivity of High-Resolution Melting in Clinical Samples.
BACKGROUND Mutation scanning provides the simplest, lowest-cost method for identifying DNA variations on single PCR amplicons, and it may be performed before sequencing to avoid screening of noninformative wild-type samples. High-resolution melting (HRM) is the most commonly used method for mutation scanning. With PCR-HRM, however, mutations less abundant than approximately 3%-10% that can stil...
متن کاملEmploying Digital Droplet PCR to Detect BRAF V600E Mutations in Formalin-fixed Paraffin-embedded Reference Standard Cell Lines.
ddPCR is a highly sensitive PCR method that utilizes a water-oil emulsion system. Using a droplet generator, an extracted nucleic acid sample is partitioned into ~20,000 nano-sized, water-in-oil droplets, and PCR amplification occurs in individual droplets. The ddPCR approach is in identifying sequence mutations, copy number alterations, and select structural rearrangements involving targeted g...
