Ion-Mobility Mass Spectrometry of Glycans and Glycopeptides Using Both Intact and Glycan Sequencing Approaches In Positive Ion Mode Facilitates Glycan Isomer and Glycan Motif Identification [PDF]
, 2020 High resolution glycan analysis has become an important part of biopharmaceutical API production and quality control. Liquid chromatography (LC) is now a well-established technique in this field but the resolution of similar isomeric glycan structures is

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Fundamentals of ion mobility spectrometry [PDF]
Current Opinion in Chemical Biology, 2018 Fundamental questions in ion mobility spectrometry have practical implications for analytical applications in general, and omics in particular, in three respects. (1) Understanding how ion mobility and collision cross section values depend on the collision gas, on the electric field and on temperature is crucial to ascertain their transferability ...
