Mass Spectrometry Proteomics Platform
The MSPP Platform of IPSiM belongs to the “Pôle Protéome de Montpellier” (PPM) that regroups regional technological facilities in proteomics analysis. This structure is certified as a proteomic platform by the GIS IBiSA on a national scale. At the institutional level, the MSPP is labeled regional platform in proteomics by INRA.
In the area of functional proteomics, MSPP offers real expertise and technological means in biochemistry, mass spectrometry and bioinformatics.
These means allow us to address many research and development projects in the quantitative analysis of proteins, the analysis of post-translational modifications, and of interactions networks.
The platform hosts programs as part of collaborations or services for a large number of academic research teams in biology, mainly French ones and for some private laboratories.
The members of the platform provide communication and training operations.
In order to define the best as possible the most adapted strategies, we advise you to contact us as soon as your project is drawn up.

The conditions for setting up and running a proteomics project on the platform are detailed in “lien vers charte PPM.
A quote will be provided upon request.
|1 LC-MS/MS analysis||150 € HT (public)||480 € HT (private company)|
The price includes :
- Proteomic training provided by the platform staff (if necessary to carry out the project).
- Materials and consumables necessary for the biochemical treatment of samples for analysis in mass spectrometry (electrophoresis gels and enzymes, for example).
- Data acquisition with mass spectrometers.
- Processing (searches in databases for example), validation and formating of results using dedicated bioinformatics tools.
For the services carried out under collaborations, part of the cost of the analyses can be covered by the platform. This participation will depend on the nature of the analyses, the number of samples processed and the degree of collaboration.

- – Research school (Sète, 2nd -5th June 2014)
A new nano-HPLC
By the end of 2016, MSPP renewed a nano-HPLC (U3000, Thermo Fisher Scientific) installed in 2003. This new generation of nano-HPLC (NCS U3500 RS, Thermo Fisher Scientific) is able to support up to 800 bars, and thus allows to use columns of greater length (50 cm), for example, in order to obtain a greater separation capacity of the peaks during an analysis
A new mass spectrometer “the Exploris 240”
In 2021, MSPP acquired a new mass spectrometer: the Exploris 240 (Thermo Fisher Scientific), which is a benchtop spectrometer allowing precursor ion selection by a high-performance quadrupole and detection by an Orbitrap Fourier transform analyzer. It is a high resolution mass spectrometer with high mass accuracy and high sensitivity. This latest generation equipment was obtained thanks to the support of INRAE (65 k€), the IPSiM and UAR BioCampus Montpellier units (small equipment requests platform 2019, 40 k€) and the MSPP’s own funds (22 k€). Co-funding from IBiSA (Call for Platforms 2019, 90 k€) and the University of Montpellier (Call for Research 2020, 50 k€) was also obtained for the purchase of this mass spectrometer.
Organisation of Mass Prot school
The Permanent Training of the PACA Center, the MassProt’InRA and Formasciences networks organize a “Proteomic – Research School” : from the preparation of the samples to the interpretation, validation and integration of the results. Strategies and practical aspects “, from Tuesday 13th June to Friday 16th June 2017 in Cannes-Mandelieu (06). The aim of this training course is to help the participants to perform their project in proteomics
