The benefits of tandem LC–MS are revealed.
This work compares at-line Protein A-MS with a standard multi-attribute method (MAM) workflow for analyzing product quality attributes (PQAs) during upstream processing.
This article explores the potential of microchip capillary electrophoresis–mass spectrometry (CE–MS) for the characterization of intact biopharmaceuticals, and how this technique can effectively be employed to monitor essential quality attributes of interest.
This instalment of “Perspectives in Modern HPLC” provides an overview of antibody–drug conjugates (ADCs) as a new class of biotherapeutics and describes their analytical characterization for quality assessment with examples from extensive applications libraries.
Comprehensive characterization of ADCs requires increasingly powerful approaches consisting of small- and large-molecule techniques.
