This Orbitrap is like-new and unused.
Excel at the most challenging of applications, including low level PTM analysis, multiplexed relative quantitation using isobaric tags, intact protein characterization, as well as MSn analysis of small molecules with the new Thermo Scientific Orbitrap Fusion Lumos Tribrid Mass Spectrometer. This system incorporates the brightest ion source, a segmented quadrupole mass filter with improved selectivity and ion transmission, Advanced Vacuum Technology for improved ion transmission to the Thermo Scientific Orbitrap mass analyzer, and ETD HD, a higher-capacity ETD fragmentation. Latest innovations include the Advanced Peak Determination (APD) algorithm for improved data-dependent experiments and two new hardware options: UVPD, a new fragmentation technique achieved with a 213 nm UV laser and 1M, which provides 1,000,000 FWHM ultra-high resolution for improved structural elucidation and quantitation of isobaric compounds.
Achieve better analysis of proteins and their post-translational modifications (PTMs) with the Thermo Scientific Electron Transfer Dissociation (ETD) option. Unlike CID, which cleaves weakly bound modifications off the peptide backbone, ETD induces fragmentation along the peptide backbone in a sequence-independent manner, leaving labile modifications linked to the peptide chain. This greatly simplifies identification of modification sites. ETD produces primarily c- and z-type fragment ions that complement the b- and y-type ions produced by CID, increasing sequence coverage and protein IDs.
- Electron transfer dissociation is a supremely useful tool for the analysis of post-translationally modified proteins. ETD capability can be added to many Thermo Scientific ion trap and Orbitrap mass spectrometers. Thermo Scientific Proteome Discoverer software includes unique capabilities to help users take full advantage of the information provided by 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
- Proteome Discoverer software includes the proprietary Z-Core database search algorithm specifically optimized for ETD spectra
- Proteome Discoverer software can easily merge complementary CID and ETD results to maximize protein sequence coverage
