Fig. 1From: Detection of KRAS, NRAS and BRAF by mass spectrometry - a sensitive, reliable, fast and cost-effective techniqueThe study workflow. All cases were tested by the KRAS LCD-array Kit and MALDI MS. If a mutation was found by the KRAS LCD-array Kit, a report was signed out. If no mutation was detected by the KRAS LCD-array Kit, that covers exclusively exon 2, Sanger sequencing has been performed for KRAS, NRAS and BRAF in exon 2–4 and a report was signed out accordinglyBack to article page
