CSF proteome mapping: Human cerebrospinal fluid LC-MS/MS, Part 5

ABSTRACT: 1.6 mL CSF from a pool of 21 neurologically healthy donors was separated into a bound and a depleted fraction using a MARS Hu-14 column. This experiment represents the bound fraction. Sample was in-solution trypsin digested and peptides were fractionated into 10 fractions by mixed-mode reversed phase anion exchange (MM(RP-AX) using a Promix MP column. Each fraction was analyzed separately by LC-MS/MS on an Orbitrap Velos Pro mass spectrometer. Resulting data was searched using SeachGui, summarized in PeptideShaker and exported to the CSF-PR.

In this study, the human cerebrospinal fluid (CSF) proteome was mapped using three different strategies prior to Orbitrap LC-MS/MS analysis: SDS-PAGE and mixed mode reversed phase-anion exchange for mapping the global CSF proteome, and hydrazide-based glycopeptide capture for mapping glycopeptides. A maximal protein set of 3081 proteins (28,811 peptide sequences) was identified, of which 520 were identified as glycoproteins from the glycopeptide enrichment strategy, including 1121 glycopeptides  ...[more]
