Analysis of Monoclonal Antibody Charge Variants by Capillary Zone Electrophoresis
20 Mar 2013This application note compares two methods for separating monoclonal antibody charge variants; capillary isoelectric focusing (cIEF) and capillary zone electrophoresis (CZE). Results show that CZE is capable of providing faster, highly reproducible separations for a representative monoclonal antibody, highlighting this method as a faster alternative to cIEF.

Capillary ElectrophoresisCapillary electrophoresis (CE) is used to separate molecules based on charge, size and hydrophobicity. Pressure, voltage or a vacuum is used to introduce the sample to fused silica capillaries. Fluorescence, UV/Vis, UV or diode array detectors are used to visualize components. Types of CE systems include capillary electrochromatography (CEC), capillary zone electrophoresis and capillary gel electrophoresis.

Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.Antibody ProductionAntibody production is essential for a wide range of applications in biochemistry and immunology. Ensuring high-quality monoclonal and polyclonal antibodies are produced is key.
