Figure 1

Scatter plot of the log₂-transformed signal intensities. Scatter plot of the log₂-transformed signal intensities of representative samples are shown in 1A - 1E. The central straight line represents the regression line and the two lines on the either sides mark the boundaries for 2-fold changes. Pearson correlation coefficient squared (r²) for each scatter plot is shown on the top. Figure-1A shows the signal intensities of two technical replicates of RNA samples. Figure-1B & 1C show correlations between corresponding FF (x-axis) & FFPE samples (y-axis) in normal breast tissue and tumor tissue respectively. Figure 1D & 1E show correlations between corresponding tumor (y-axis) and normal (x-axis) tissue from same patient using FF and FFPE samples respectively.
