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.
