The colors corresponding to decreasing abundance are in the order of red, black,
and green. Four biological replicates of each organ and four technical replicates of
each digest were performed. Proteins had to be identified in at least three of four
technical replicates of one organ type. Two random proteins replicated, for a false
positive rate of 0.16% at the protein level.
