Scientists that have worked with peptides understand that peptide quantification can be challenging. One of the keys to successful peptide analysis is thorough and selective sample preparation. Sample preparation improves various aspects of chromatography and… Read more >
What does “intelligence” mean in the context of biopharma analysis? Given the complex setting, much of the answer comes down to the task a user needs to complete, along with the question of who exactly… Read more >
There’s no question that we’ve entered the age of smart technology. Your phone, your home, your refrigerator, even your light bulbs are all getting smarter. Such technologies do more and more to run themselves, removing… Read more >
In late January, I traveled to WCBP (Well Characterized Biological Products), an industry conference that is hosted every year by the CASSS organization. It serves as a forum that brings together biopharmaceutical industry professionals and… Read more >
Its great promise for routine monitoring of biologic drugs begs the question: Just when will LC-MS analysis become a true bedrock analytical tool for scientists and technicians throughout biopharma?
Analytical data can be so much more than a historical point in time documented in a single report. In fact, biopharmaceutical organizations can use LC-MS data to build a continuum of compliance.
We listened and learned how scientists separate mAbs and ADCs; then we designed a novel column for LC-MS bioseparations A critical step toward the prolific and successful use of monoclonal antibodies (mAb) as biotherapeutics occurred… Read more >
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.
“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.
