  2. Trmt*Day denotes the treatment and day of the observed change in protein spot
  3. CPP3, component 3 of the proteose peptone
  4. Data are presented as the least square mean ± standard error of the mean (LSM ± SEM).
  5. Direction indicates the up-or down-regulation of the protein spot on day 2 or 14 pi, compared to baseline.
  6. Spot I.D. number refers to protein spot number assigned by the Melanie software. Spots that were excised and identified by LC-MS/MS are indicated in parentheses.
