Abstract: dia-PASEF® (Meier et al., 2020; 1) merges the benefits of data-independent acquisition (DIA) with the advantages of ion mobility in proteomics experiments (Meier et al., 2018; 2). The ion mobility dimension improves the alignment of precursor and fragment spectra. In this study, we applied a dia-PASEF workflow in combination with an Evosep One (Evosep, Bache et al., 2018, 3) chromatographic system for high-throughput analysis of eHAP cell line digests, while quantifying spiked-in, oxidized target peptides in SpectronautTM (Biognosys, Bruderer et al., 2015, 4) on different gradient lengths.Summary: In this study, we applied a dia-PASEF workflow in combination with an Evosep One (Evosep, Bache et al., 2018, 3) chromatographic system for high-throughput analysis of eHAP cell line digests, while quantifying spiked-in, oxidized target peptides in SpectronautTM (Biognosys, Bruderer et al., 2015, 4) on different gradient lengths.References: 1: https://pubmed.ncbi.nlm.nih.gov/33257825/
