Since 2010, the MAS Facility has organized Workshops in Mass Spectrometry-Based Proteomics. These events, which have the support of FAPESP, promote a continuing formation for the present and future users of the Laboratory of Mass Spectrometry and for researchers in the areas of proteomics and mass spectrometry. They are also an opportunity for the exchange of scientific information about research projects in these areas, besides being an incentive for the formation of new nucleus for research in mass spectrometry and proteomics. These workshops contribute to the promotion of the exchange of new technologies, creating a closer relationship between Brazilian and international researchers and the diffusion of knowledge in the scientific community.
