The Plateforme d’Analyse Protéomique de Paris Sud-Ouest (PAPPSO facility) provides research teams with equipments, skills and expertises in the field of proteomics, to allow them to respond to the most simple questions (identification of proteins from an organism the genome of which is entirely sequenced) as well as to complex questions (protein quantification in complex samples, dynamics of post-translational modifications,…) in the framework of collaborative projects and contracts.

The PAPPSO facility arose by merging two complementary platforms. One of them is located in Jouy-en-Josas and is specialized in prokaryote proteomics, while the other is located in Gif-sur-Yvette (Le Moulon) and specializes in plant proteomics. The complementarity of their expertise allows the PAPPSO facility to propose different types of analyses, that are based either on protein or peptide separation or on shotgun techniques with or without isotopic labelling.

PAPPSO is specialized in high throughput proteomics (quantitative analysis of large cohorts of samples) and in the analysis of highly complex samples (métaprotéomics). The platform develops bioinformatics tools that allow the processing of these experiments and provides asistance to users for data interpretation.

PAPPSO is open to national and international collaborations and has been labelled as such in 2009 (IBiSA label).

PAPPSO thanks all the partners that financially support the facility.
