ProteomicsUltraviolet Photodissociation of ESI and MALDI generated protein ions on a Q-Exactive mass spectrometer
UVPD was implemented on an Orbitrap Q-Exactive plus equipped with a ESI/EP-MALDI. UVPD of MALDI generated ions was benchmarked against MALDI-ISD, MALDI-HCD and ESI-UVPD. MALDI UVPD outperformed MALDI HCD and ISD efficiently sequencing small proteins ions.

ProteomicsThe Q Exactive HF, a Benchtop Mass Spectrometer with a Pre-filter, High Performance Quadrupole and an Ultra-High Field Orbitrap Analyzer
The quadrupole Orbitrap mass spectrometer (Q Exactive) has made a powerful proteomics instrument available in a benchtop format. It significantly boosted analyzable proteins per hour and has now evolved into a proteomics analysis workhorse for many laboratories. Here we describe the Q Exactive Plus ...

ProteomicsIdentification of peptides from E-Jiao
E-Jiao is a traditional Chinese medicine. In this project, we used Q Exactive Orbitrap Plus to identify the peptides from E-Jiao. We also used the QE Plus to investigate the E-Jiao peptides in rat blood.
