ABI Voyager DE PRO MALDI tof mass spectrometer

The MALDI tof mass spectrometer measures the masses of the tryptic peptides generated by the MassPrep station. Matching these peptide masses against a database provides protein matches which using bioinformatic packages can provide information about the protein of interest in a particular biological process. Further information about proteins which cannot be identified by MALDItof can be obtained by submission of the tryptic peptides to nanoflow HPLC and ESI mass spectrometry using the ABI Q Trap (see Mass Spectrometry section).
