This study aimed to establish and validate a robust untargeted lipidomics workflow for the analysis of human serum using reversed-phase liquid chromatography coupled to trapped ion mobility spectrometry time-of-flight mass spectrometry (RP-LC-TIMS-TOF MS). Commercial pooled human serum was used a...

In bottom-up proteomics, peptides are separated by liquid chromatography with elution peak widths in the range of seconds, while mass spectra are acquired in about 100 microseconds with time-of-fight (TOF) instruments. This allows adding ion mobility as a third dimension of separation. Among several...

Proteomic analysis was conducted to identity proteins associated with the PilQ secretin complex in Pseudomonas aeruginosa. Samples were analyzed using a trapped ion mobility spectrometry time-of-flight (TIMS-TOF) mass spectrometer. The dataset includes raw mass spectrometry data and processed identi...

Data independent acquisition methods have become increasingly popular in mass spectrometry (MS)-based proteomics because they enable parallel and continuous acquisition of fragment spectra. However, these advantages come with the challenge of correctly reconstructing the precursor-fragment relations...

Data-independent acquisition (DIA) methods have become increasingly attractive in mass spectrometry (MS)-based proteomics, because they enable high data completeness and a wide dynamic range. Recently, we combined DIA with parallel accumulation – serial fragmentation (dia-PASEF) on a Bruker trapped ...

We introduce a novel approach, termed time-segment acquisition (Seg), to enhance the identification of peptides and proteins in trapped ion mobility spectrometry (TIMS)-Time of flight (TOF) mass spectrometry. Our method exploits the positive correlation between ion mobility values and liquid chromat...
