Figure 1

Base peak (BPC) and extracted ion chromatographs (EIC; mass over charge (m/z) value of 692.4) from one healthy plasma sample analyzed on three different dates using the LC-MS platform. Both the overall BPC and randomly selected EIC are consistently represented in the sample over time and between tryptic digests. The green chromatographs are from the original sample digest (10/27/2008) run on the day of the tryptic digestion, red traces are from the same sample digest stored at -80°C for 22 months (run on 8/30/2010), and the blue traces are from a new tryptic digest of the same plasma sample (digested and run on 8/31/2010). The corresponding MS scans illustrate summed spectra (RT 38.4-39.9 minutes) associated with the major peak from each of the EICs. Insets indicate similarity even for a very low intensity region of the spectra.
