There are two primary multi-attribute monitoring (MAM) assay choices for biologic development and QC: subunit protein mass analysis and peptide mapping by LC-MS. Here we explore how peptide mapping LC-MS MAM workflows are being used.
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.
A new approach to stationary phase chemistry for reversed-phase LC analysis of proteins, including monoclonal antibodies and antibody drug conjugates, delivers higher fidelity data especially for MS-based peak identification.
If data can throw your biotherapeutic development program into chaos, it can also help move you forward. Let’s see how.

In biotherapeutics, the state of glycosylation has a direct and pronounced effect of the structure, stability, serum half-life, immunogeneicity and bioactivity of the molecule, and constitutes a critical quality attribute (CQA). In our study, characterizing and comparing the glycosylation profile of infliximab began by examining the glycosylation profiles from intact and reduced subunit mass data.
