Differentially expressed spots between CR and CNR with p-value <0.05 and fold change >1.5.

<p>No is the spot number; Fold is the fold change in expression; p is the p-value associated with the fold change in expression; Score and expectation value (E-value) indicate the confidence of protein identification; Match is the number of matching peptides; mW/pI is the theoretical molecular weight and isoelectric point as calculated from Mascot database; all spots were confirmed with tandem mass spectrometry.
