The PCL has a Bruker Ultraflextreme MALDI-TOF mass spectrometer equipped with delayed extraction and reflectron capabilities which is used for routine high mass accuracy analysis of peptides (<3 kDa). The instrument can also be operated in linear mode for protein analysis (>3 kDa). The Ultraflextreme is capable of Top Down and Bottom Up peptide mass fingerprinting. It is equipped with a 2000 hertz laser that makes it also capable of Imaging Mass Spectrometry. The lab has all relevant software for mass measurement, MASCOT searching with BioTools and FlexImaging and SciLs software for image analysis.
