Features of the ETD:

  • ETD preserves labile PTMs, allowing straightforward identification of the peptide sequence and the site of modification>
  • For top-down analysis, ETD can be combined with proton transfer reaction (PTR) which dramatically simplifies spectra from intact proteins
  • For workflows that include low-mass isobaric mass tags, ETD can be combined with pulsed-Q dissociation (PQD) which eliminates the normal low-mass cutoff
  • ETD can be added to most Thermo Scientific LTQ-series ion trap and hybrid ion trap-Orbitrap mass spectrometers

This Thermo LTQ Orbitrap with ETD and LTQ XL Mass Spectrometer comes fully tested and refurbished from GenTech Scientific.
