Figure 2.
Comparison of a 87-bp PCR amplification approaches for (A) a low-abundance (3%) Tm-increasing mutation (PFSK-1 cell-line DNA, c.823T > G; p.Cys275Gly), (B) a low-abundance (3%) Tm-equivalent mutation (HCC1008 cell-line DNA; c.841G > C, p.Asp281His), (C) a low-abundance (3%) Tm-reducing mutation (HCC2218 cell-line DNA; c.847C > T, p.Arg283Cys) and (D) a low-abundance (3%) Tm-reducing one base pair deletion (c.845del, p.Arg282del) in DNA from a clinical lung adenocarcinoma specimen. Representative chromatograms are presented; estimates of fold improvement are based upon multiple evaluations.
