New Application Note on Antibody Oxidation Analysis

A Rapid LC-MS Assay for Monitoring of mAb Oxidation at the Subunit Level
 
Methionine oxidation is considered a critical quality attribute of therapeutic antibodies and may impact the clinical safety and efficacy. Therefore, monitoring of methionine oxidations is required during the discovery, development, and production of therapeutic antibodies. Traditional methods to characterize oxidation rely on tryptic peptide mapping and LC-MS, a labor intensive and time- consuming process that generates large data sets and requires trained and skilled manual interpretations.
