Abstract
The approved multi-user equipment was installed in August 2011 at Mass Spectrometry Laboratory, located at Brazilian Biosciences National Laboratory (LNBio), ABTLuS-CNPEM. The multi-user equipment is ETD enabled Orbitrap Velos instrument (Thermo Fisher Scientific) connected to nanoflow liquid chromatography EASY-nLC II system (Proxeon Biosystem) through a Proxeon nanoelectrospray ion source. These instruments combine mass accuracy and high resolution of the Orbitrap mass analyzer, with the increased sensitivity of LTQ Velos. It can provide multiple fragmentation techniques: CID, HCD and ETD, which have extended the possibilities within tandem mass spectrometry, increasing the speed and confidence of identification of large-scale complex proteomes, binding partners and post-translational modifications, analysis of cross-linked complexes to map protein interaction, and likely quantitative proteomic approaches. The equipment is available to the Brazilian scientific community in the same manner as is the other multi-user equipment of the Mass Spectrometry Laboratory. The Laboratory started the operation in continuous mode, in terms of the submission of proposals and analyses in June 2009. One of the characteristics of the Laboratory is that users are provided with technical support in the operation of the mass spectrometers and the data analysis, as well as with training in the area of mass spectrometry/proteomics that is fundamental for the development of individual research. The implementation of the new cutting-edge technology ETD enabled Orbitrap Velos instrument at Mass Spectrometry Laboratory has included the Brazilian scientific community in the international panorama of competitiveness in the area of mass spectrometry/ proteomics.
