A Combined Shotgun and Targeted Mass Spectrometry Strategy for Breast Cancer Biomarker Discovery.

Data from ProteomeXchange, PXD ID: PXD001685. File: B08-07165_c.mzml. Published as part of J Proteome Res. 2015 Jun 5 . From the Abstract: {{i} ... Eighty breast tumors, stratified for estrogen receptor status and development of distant recurrence (DR - ), were collected. After enrichment of N-glycosylated peptides, label-free LC-MS/MS was performed on each individual tumor in triplicate. In total, 1515 glycopeptides from 778 proteins were identified and used to create a map of the breast cancer N-glycosylated proteome. Based on this specific proteome map, we constructed a 92-plex targeted label-free LC-SRM panel ... {{/i}}
