For protein biotherapeutics, the generation of a manufacturing cell line to support product development is critical. The product quality of hundreds of cell-lines per program are screened by mass-spectrometry (MS). However, the nature of MS data impedes the implementation of end-to-end automation of analysis. Here, we describe the design and implementation of automated workflows for intact MS data processing and reporting.

Janssen has developed an end-to-end solution for the support of cell line development. Along with a Thermo mass spectrometry platform and robotics that feed Byos software, Hirsh Nanda's lab is able to truly implement the screening of hundreds of cell lines from bioreactors in less time than before. See the automation in action at Thermo's user meeting in the 'From Discovery to QC' section

Complex glycoprotein analysis: Glycosylation, including glycan structures and occupancy, plays a vital role in the stability and efficacy of protein-based vaccines. Here, the ability of latest ECD technology to characterize a vaccine protein with multiple glycosylation sites was examined. Poster with Janssen and Sciex

Disulfide bond mapping is notoriousy challenging and in protein characterization has often required numerous experiments. Here, Agilent and e-Msion use ECD technology to use CID and ECD together, and annotate the spectra with Byos software.
7-Jun-22 Poster TP 426
Characterization of disulfides and trisulfide bonds is challenging and for bispecific antibodies the level of complexity is even higher. ECD fragmentation is supported in Byos and MS/MS spectra obtained by ECD provided a much higher level of sequence information compared to CID.

Accurately mapping deuterium locations in HDX relies partially on tracking deuterium during the chromatography separation which have had to be swift in the past. This study uses time-warping in long LC-MSMS gradients with Byos software to map back to HDX-MS experiments, and therefore allow the study of larger complexes.

Adeno-associated viruses (AAVs) are a crucial tool for development and delivery of cutting-edge gene therapies. We developed liquid chromatography mass spectrometry (LC-MS) methods for AAV characterization for host cell protein analysis (HCP) and sequence variant analysis (SVA). In addition, orthogonal methods of subunit and peptide mapping were compared directly to capture discrepancies.
This vendor agnostic protocol requires no method development, can be easily adopted for Oligos characterization workflows such as intact mass analysis, analysis of impurities and degradation products.
