Multi-Attribute Monitoring: The Expanding Role of Mass Spectrometry for mAb Subunit Analysis

By June 1, 2018

Two MAM approaches for biotherapeutic analysis are being implemented today; one focused on the analysis of monoclonal antibody (mAb) subunits, and the other focused on the analysis of peptides from a protein digest (peptide mapping workflow). Both have their advantages and disadvantages. Here, we explore MAM for mAb subunit analysis.
