N-linked glycosylation is a common post-translational modification on many antibody-based therapeutics, and has been linked to safety, stability and activity. Modification should therefore be monitored and controlled.

During this webcast, our expert Michael Walker discusses peptide mapping and middle-up mass spectrometry as characterization techniques that give relative levels of different glycoforms at specific sites, and compares to more common methodologies of enzymatic stripping and fluorescent labelling.
