Imaged capillary electrophoresis isoelectric focusing (iCE) profiles of mAb X lots and mAb X’ (a) before and, (b) after CPB digestion. The lysine variant peaks disappeared post CPB digestion (indicated with arrows). (c) HIC profiles of mAb X lots and mAb X’ showing the relatively higher hydrophilicity of mAb X’. mAb X sourced from external agencies are labelled as mAb X2.
