Aug 15, 2005 | Bruker Daltonics introduced the Electron Transfer Dissociation (ETD) module for its high-capacity ion trap mass spectrometer, the HCTultra. The ETD is a unique new peptide and protein fragmentation technique that preserves functionally important post-translational modifications, such as phosphorylation or glycosylation. ETD MS/MS spectra of peptides can be collected on-the-fly during LC/MS/MS runs and due to its non-ergodic nature, ETD creates clean MS/MS spectra with intact PTMs. Using the HCTultra and the ETD module, one can achieve complete amino acid series down to immonium ion masses, without the low-mass cutoff traditionally encountered in ion-trap MS/MS.
