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.
“Assuming continuous improvement is a worthy goal, there is every reason to improve validated chromatographic methods if you’re working with the right instrument technology,” says Eric Grumbach of Waters. See what that means for developing and transferring methods for biologic drugs.
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.
A thousand small delays and opportunities for error can snowball over the years of a complex biotherapeutic drug development program. They add up to lost time and increased risk in an endeavor that has little tolerance for either. It doesn’t have to be this way.
To get the most out of recent innovations in biopharma development and QC such as multi-attribute monitoring, it’s time to better connect the systems that manage biopharma data. This series explores the what, the why, and the how of better biopharma data.
If data can throw your biotherapeutic development program into chaos, it can also help move you forward. Let’s see how.
“One of the important reasons that we use Waters LC-MS instruments is that beyond the quality of the products, Waters delivers a high degree of technical training. This provides us with the knowledge and confidence that we can solve our complex research questions.” comments Triskelion’s Richard Bas.
“If You Build it, He Will Come” Urged on by a voice no one else could hear, Ray Kinsella, played by Kevin Costner in the movie Field of Dreams, cleared a few acres of corn… Read more >
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.
