Rigorous characterization of biotherapeutics, and monoclonal antibodies in particular, is a challenging task in terms of ensuring safety, efficacy, and potency of a therapeutic agent because of structural heterogeneity during cell culture, purification and storage. In this work, we used microfluidic capillary electrophoresis-mass spectrometry to analyze intact monoclonal antibody and assess the root cause of increases in acidic and basic variants under stress at high temperature. The antibody was analyzed at multiple lev
