Application Note: A direct IEX-MS method for the detection of mAb charge variants
25 March 2020

This application note demonstrates a direct IEX-MS method with broad utility for the successful detection of mAb charge variants. Platform methods can be easily developed using the BioResolve SCX mAb Column, IonHance CX-MS pH Concentrates, and BioAccord LC-MS System which provide robust and reproducible separations along with high quality mass spectra in the elucidation of various mAb-charge variant species.
