优点: KRAS and BRAF are oncogenes involved in the epidermal growth factor receptor (EGFR) signaling pathway that controls cell proliferation, differentiation and apoptosis. Mutations in the KRAS and BRAF oncogenes are frequently found in human cancers, such as colorectal cancers and non-small cell lung cancers. The Signature® KRAS/BRAF Mutations assay is a research tool for the rapid detection of mutations in genomic DNA extracted from human cell lines or fresh, frozen or fixed tissues.
