Identification rates and overlap of identified proteins of FF and RL stored samples. (a): Mean count of peptide-spectrum matches (PSMs); (b): Mean count of peptides identified, (c): Mean count of total number of proteins identified (Proteins), mean count of protein groups assembled by Scaffold (Protein groups), and mean number of proteins uniquely identified in one replicate (Uniquely identified proteins); (d): Overlap of bacterial proteins identified in at least two replicates in both storage conditions. Means are based on three replicates each. Error bars represent the standard deviation. FF: flash frozen; RL: RNAlater-treated.
