Effect of storage time on peptide yield. a Average peptide yield per sample at each RTR. b Total peptide extraction yield (µg) from SEER specimens versus specimen age, evaluated by BCA assay. Each point represents total yield from five 10-µm FFPE sections, scraped and pooled in a single tube for sample processing. Different colors are used for each RTR. c Peptide yield normalized to tumor volume (surface area × 0.01 mm depth) versus time in storage for the two RTRs reporting tumor dimensions
