Figure 3: Distribution of signal intensities and standard deviations. (a) Each plot is a dot plot showing the means and standard deviation of the signal for each target site, with control samples on the left and case samples on the right. Red vertical lines indicate the data for either control sample #5 or case sample #5 (b) Kernel density estimates are shown that correspond to the dot plots in (a) Samples are color coded as follows:— sample #1, — sample #2, — sample #3, — sample #4, — sample #5, — sample #6, and — sample #7.
