Bruker Introduces Protein PTM Discovery Tool on HCTultra Ion Trap

Bruker Daltonics announced a commercial electron transfer dissociation (ETD) module for its high-capacity ion trap mass spectrometer, the HCTultra. ETD is a new peptide and protein fragmentation technique that preserves functionally important post-translational modifications, such as phosphorylation or glycosylation. With ETD in a high-capacity ion trap, protein scientists can sequence peptides easily, and in addition they can simultaneously identify both the type and location of various post-translational modifications (PTMs).
