^aNumber of peptides that match the theoretical digest of the primary protein identified
^bQuality score of peptide-mass fingerprint matches and of MS/MS peptide fragment ion matches, if MS/MS data were generated
^cQuality score of only MS/MS peptide fragment ion matched, if MS/MS data were generated
^dSignificant score threshold. For each given database, a hit with an “MS & MS/MS Score” above the indicated value was considered a significant identification (p < 0.05). Only hits with an “MS & MS/MS Score” above this value are reported
