Instrumentation

Lumos

Thermo Scientific Orbitrap            Fusion Lumos Tribrid with             Waters NanoAcquity UPLC

~quantitative proteomics~

A quadrupole-Orbitrap-linear ion trap tribrid mass spectrometer employing HCD, CID and ETD fragmentation options. Instrument is equiped with a FAIMS PRO source for atmospheric ion mobility separations providing improved analyte selectivity and expanded proteome coverage. Analysis of complex protein digests including identification of post-translational modifications, covalently bound protein-drug adducts, and chemically cross-linked peptides. Ideal for stable isotope label (e.g. SILAC, TMT) or label-free (peptide peak area) quantitative proteomics workflows.
