PAPPSO offers the following services on plant or animal matrices, microorganisms, culture supernatants, laser microdissected sections, or extracellular vesicles. These services can be provided under fee-for-service activities, research contracts, or public-private partnership agreements (note that not all services are available under fee-for-service).

  • Peptidomics Analysis Services:

    • Identification and relative or absolute quantification of endogenous peptides

  • Proteomics Analysis Services:

    • Identification and characterization of purified proteins or proteins in low-complexity mixtures
    • Identification and relative, global, or targeted quantification of proteins in complex mixtures
    • Identification and relative quantification of post-translational modifications (e.g., phosphorylation, N-terminal acetylation)
    • Identification of protein interactors after co-immunoprecipitation or proximity labeling

  • Metaproteomics Analysis Services:

    • Global quantitative analysis of proteomes from microbial communities (e.g., gut or rhizosphere microbiota)

Our services include:

  • Guidance on sample preparation and experimental design (for extraction from plant matrices and microbiota: please contact us)
  • Sample preparation for mass spectrometry analysis
  • Data acquisition by mass spectrometry in DDA (data-dependent acquisition) or DIA (data-independent acquisition) mode
  • Bioinformatics processing and statistical analysis of the data
  • Support in result valorization (data upload to public repositories, contribution to manuscript writing)
