Proteomics utilizes different tools to allow the analysis of the complete proteome of an organism and complex protein mixtures. The questions tackled by proteomics include the identification of proteins, to the analysis of quantitative variations between different conditions, the analysis of post-translational modifications and the study of protein-protein interactions.

The aim of the proteomic platform PAPPSO (Plateforme d'Analyse Proteomique de Paris Sud-Ouest) is to help individual scientists and research teams by providing equipments and utilizing scientific and technical skills in mass spectrometry to answer their scientific questions. The questions range from simple (protein identification from an organism with sequenced genome) to the complex (protein abundance, variation, quantification, dynamics of post-translational modification) in the framework of collaborations or contract works.

PAPPSO is formed with the merger of associations of two complementary technical capabilities. One of them is located in Jouy-en-Josas, which specializes in prokaryotes and the other is located in Moulon, more specialized in vegetal biology. The complementarity of their expertise allows PAPPSO to perform research and offer the proteomic analysis based either on protein separation in gel or on shotgun type techniques.

PAPPSO is a completely open platform and has been labeled as such in 2009.

PAPPSO is endowed with a scientific committee.

PAPPSO thanks all the partners who have financially supported the platform.
