We have applied conformer-selective IR-UV double-resonance photofragment spectroscopy at low temperatures in an ion trap mass spectrometer for the spectroscopic characterization of peptide fragment ions. We investigate b- and a-type ions formed by collisio ...
RATIONALE Similar to other mass spectrometric technologies based on ion trapping in a spatially restricted area, the performance of Orbitrap Fourier transform mass spectrometry (FTMS) is affected by the interaction between the trapped ion clouds. One of th ...
The interaction between oxaliplatin and the model protein ubiquitin (Ub) was investigated in a top-down approach by means of high-resolution electrospray ionization mass spectrometry (ESI-MS) using diverse tandem mass spectrometric (MS/MS) techniques, incl ...
Molecular and macromolecular structure analysis by high resolution and accurate mass spectrometry (MS) is indispensable for a number of fundamental and applied research areas, including health and energy domains. Comprehensive structure analysis of molecul ...
We present a novel, hybrid ion trap/time-of-flight mass spectrometer that is based on a planar multipole design. Compared with Paul trap/time-of-flight instruments, this design possesses the principal advantages of higher injection efficiency and more homo ...
Results of the mechanistic studies of free-electron based fragmentation methods addressing peptide and protein structure analysis with mass spectrometry (MS), electron capture dissociation (ECD) and electron ionization dissociation (EID), are presented. Se ...
Tissue transglutaminase (tTGase) catalyzes both deamidation and transamidation of peptides and proteins by using a peptidyl glutamine as primary substrate. A precise consensus sequence for the enzyme is unknown and the ratio between deamidated and transami ...
Site-specific reproducibility and repeatability of electron capture dissociation (ECD) in Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) are of fundamental importance for product ion abundance (PIA)-based peptide and protein struct ...
Sidebands in mass spectra are an intrinsic feature of Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). Appearance of the sidebands there is detrimental for the analytical performance, especially in case of complex mixtures analyzed ...
Combined with high and ultra high pressure liquid chromatography, mass spectrometry-based peptide and protein structure analysis requires high resolution and mass accuracy achievable within short ion detection time. Although Fourier transform ion cyclotron ...
