N-glycans are omnipresent in the Fc region of monoclonal antibody products. Modifications to a glycan profile can impact a protein’s stability/folding, binding affinities, effector functions, clearance rates, and/or immunogenicity.
Using the right practical tools, de novo sequencing now can be easily turned into an in-house, higher throughput procedure with extremely high confidence.
John Reed covers the ins and outs of PTM analysis. He touches on peptide identification and the use of standard curves and weighted averaging of XICs - and a little bit of ice cream.
Why are we interested in virus glycosylation in general? Max Crispin from the University of southampton gives us an intrudction to the topic as well as a deep dive into the elucidation of the SARS-CoV-2 Glycan shield
Comparing batches? Assessing digestion completion? Tracking over-alkylation? Learn about the rational for the types of dashboard constructed to monitor these important aspects of laboratory operations.
Marshall Bern details the usage of Intact Mass deconvolution in order to tease apart the complex glycosylation profiles of EPO
Jerome Jonveaux describes peptide and intact workflows developed for quantification of PTMs and comparison of AAV samples
The novel workflow for AdV VP analysis affords substantially lower analysis times than traditional peptide mapping methods, which require the use of several proteases and long sample processing for sufficient in-depth characterization.
