Monitoring of On-column Methionine Oxidation as Part of a System Suitability Test During UHPLC–MS/MS Peptide Mapping

Long-term column use can lead to on-column methionine oxidation during LC–MS/MS peptide mapping of antibody-based biotherapeutics. Following the approach described here minimizes the risk of measuring oxidative artifacts, and helps generate high quality data to provide reliable quantitative information about product-related heterogeneities.
