^aMascot computes a score based on the probability that the peptides from a sample match those in the selected protein database. The more peptides Mascot identifies from a particular protein, the higher the Mascot score for that protein.
“+” Means those proteins that only observed in the 2-DE map of M. hyopneumoniae strain 168, which means its expression level in strain 168L is very low.
