  1. Five technical replicates of a P. multocida sample were spiked with different concentrations (3, 6, 12, 120, & 1200 pmol) of standards. Pairs of the spiked samples were used to represent "control" and "treatment" in simulated experiments. Any non-spiked proteins that are identified as differentially expressed are false positives (see Figure 4).
