Figure 1

Expression of HER-2/neu RNA by real-time PCR (LightCycler). Amplification curve shows serial dilutions of an initial amount of SK-BR-3 RNA: 1 (3333 cells), 2 (333 cells), 3 (166 cells), 4 (33 cells), 5 (16 cells), 6 (1.6 cells) and 7 (0.6 cells). Inset, standard curve plot of the log of SK-BR-3 RNA cells numbers vs Cp. The standard curve shows seven orders of linear dynamic range (y=−3.67x+33.071; R2=0.9983).
