Characterization of ADCs by Capillary Electrophoresis
Capillary electrophoresis (CE) is a highly efficient separation technique that resolves ions based on their electrophoretic mobility in the presence of an applied voltage. It has been broadly applied for characterizing biotherapeutics including ADCs. In this chapter, step-by-step procedures for characterizing ADCs using CE will be described with focus placed on reduced and non-reduced capillary electrophoresis sodium dodecyl sulfate (CE-SDS) for purity determination and imaged capillary isoelectric focusing (iCIEF) for charge heterogeneity analysis.
