Abstract: Characterization of therapeutic proteins such as monoclonal antibodies requires a broad range of analyses including the confirmation of the protein sequence as well as the identification of post translational modifications such as glycosylation. A common workflow for sequence confirmation is the peptide mapping approach, in which tryptic peptides are sepa rated by reversed phase chromatography and further analyzed using high resolution MS/MS. Typically, N linked glycans are then analyzed in a subsequent dedicated step after release and reducing end labelling. Here, we describe a new method to determine glycan profiles directly from peptide maps using analytical LC and the new VIP HESI ion source and fast MS/MS spectra acquisition using trapped ion mobility separation in a timsTOF Pro 2 instrument.Summary: Here, we describe a new method to determine glycan profiles directly from peptide maps using analytical LC and the new VIP HESI ion source and fast MS/MS spectra acquisition using trapped ion mobility separation in a timsTOF Pro 2 instrument.References: 1: Hilliard M, Alley WR Jr, McManus CA, Yu YQ, Hallinan S, Gebler J, Rudd PM (2017). mAbs, DOI: 10.1080/19420862.2017.1377381
