Figure 4

Extracted ion chromatograms illustrating five MRM transitions/peptide for the identification of putative cancer biomarkers in whole cellular extracts. Conditions: MCF-7 whole cellular extracts were digested with trypsin, cleaned-up with SPEC-PTSCX and SPEC-PTC18 cartridges, and analyzed by a ~4 h long LC-MS/MS gradient. The top-down order of EICs reflects the order of the five transitions shown in Table 1.
