All mapping results are freely available via the new CSF Proteome Resource ( ), which can be used to navigate the CSF proteome and help guide the selection of signature peptides in targeted quantitative proteomics.Īuthor contributions: A.G., H.V., E.O., K.M., J.A.O., H.B., and F.S.B. An overlap of 877 proteins was found between the two body fluids, whereas 2204 proteins were identified only in CSF and 173 only in plasma. From parallel plasma samples, we identified 1050 proteins (9739 peptide sequences). To our knowledge, this is the largest number of identified proteins and glycopeptides reported for CSF, including 417 glycosylation sites not previously reported. 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 and their glycosylation sites.

Reshake PRIDE: re-analyze public datasets in PRIDE as if they were your own.Īll data can also easily be exported for follow up analysis in other tools.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.
