Separation of Fucosylated, non-Fucosylated and Complex Carbohydrates Associated with Monoclonal Antibodies using Capillary Electrophoresis

3 Dec 2012

In order to gain a comprehensive understanding of therapeutic monoclonal antibody function, it is necessary to characterize the associated glycosylation. This application note from Beckman Coulter presents a method that enables fucosylated, afucosylated, sialylated and complex antennary oligosaccharides to be differentiated from one another. The work suggests that capillary electrophoresis can be used to successfully separate and quantify a wide array of N-linked oligosaccharides associated with monoclonal antibodies.

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.GlycobiologyGlycobiology encompasses research into the biological functions, synthesis and structures of glycans, including glycoproteins, glycolipids, proteoglycans and free oligosaccharides. Mass spectrometers and their software are commonly used in the study of glycobiology, along with structure predicting tools, chromatography and NMR.GlycoproteinsGlycosylationMonoclonal AntibodiesMonoclonal antibodies (mAbs) are lab-made molecules that can bind to specific antigens on cells, making them highly effective in treating cancers, autoimmune diseases, and infections. These targeted therapies are transforming the treatment landscape for many conditions.
