CSF proteome mapping: Human plasma LC-MS/MS, Part 7

40 µL plasma from a pool of 20 neurologically healthy donors was separated into a bound and a depleted fraction using a MARS Hu-14 column. This experiment represents the depleted fraction. Sample was in-solution trypsin digested and peptides were fractionated into 67 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.
