Figure 2

Effect of injection amount on the oxidation event per peptide measurements of three different proteins: (Top) hen egg white lysozyme, (Middle) horse heart myoglobin, and (Bottom) COSMC. Solid and outlined columns represent 2 and 5μL injection volume, respectively. Error bars represent the oxidation events per peptide standard deviation. A two-tailed Student’s t-test was performed to test statistical significance between the OEP of each peptide at two different injection amounts, and found no statistically significant differences (α = 0.05).
