Proteored Multicentric Experiment PME11 - Phosphoproteomics
PME11 - Phosphoproteomics PME11

We present the new multicentric study within ProteoRed Network.


The final goal of the study is to allow each laboratory to assess its ability and improve their protocols for phosphopeptide analysis.

The study should allow:

  • Evaluating the performance and reproducibility of phosphopeptide enrichment procedures.
  • Testing the usefulness of phosphopeptide mixture standard to set up, monitor, and troubleshoot phosphopeptide analysis methods.

The samples to be analyzed in the study (PME11-A1, A2, A3) consist of a yeast tryptic digest (C-18 purified), spiked-in with three different concentrations of a mixture of 20 human phosphopeptide standards (Phosphomix 1and 2 from Sigma-Aldrich, see attached specification file), containing light isotopes.
