Figure 1From: KRAS analysis in colorectal carcinoma: Analytical aspects of Pyrosequencing and allele-specific PCR in clinical practice KRAS analysis by Pyrosequencing. Representative examples of Pyrosequencing KRAS analyses of codons 12 and 13 (A-D) and codon 61 (E-F). Codon 12, 13 wt (A); codon 13 mutation GGC>GAC (B); codon 12 mutation GGT>GAT (C); codon 12 mutation GGT>GAT in DNA from tissue with less than 10% tumor cells (D); codon 61 wt (E), and codon 61 mutation (F).Back to article page
