Summary of peptides susceptible to degradation by indirect solar disinfection (UVA+RB). The graph shows the ratios of the peptides from treated (UVA+RB) to untreated (CTL) samples, measured using the SILAC method. These peptides belong to three HAdV-2 proteins: fiber protein (A), hexon protein (B), and penton protein (C). Different data points indicate replicate samples. The data are visualized in box plots based on at least four replicate samples, where the upper boundary represents the 75th percentile, the line represents the median, and the lower boundary represents the 25th percentile.
