Percentage (%) of change was calculated dividing the post-treatment mean intensities over the pre-treatment mean values.
A minimum MS score O64 was considered significant.
A minimum of two significant MS/MS peptide fragments was considered to assign an ID for a spot.
Spot G was identified as complement C4B precursor based on the protein score obtained by ProteinPilot.
