| الوصف: | The characterization of the N-glycan portion of antibodies has been the subject of several studies involving mass spectrometry. In this article, a workflow is presented that starts with the expression of a monoclonal antibody (EG2-hFc) in Chinese hamster ovary cells and continues with Protein A purification of the antibody. Then the protocol continues with gel electrophoresis. Bands containing the heavy chain are cut and isolated from the gel followed by tryptic digestion to obtain peptides and glycopeptides. The enrichment of glycopeptides by C18 chromatography is described followed by characterization using positive and negative modes MALDI-MS and MS/MS. An exoglycosidase, beta-galactosidase, is used to verify anomericity of linkages in the glycan portion of glycopeptides. In the last step, glycans are detached from glycopeptides using PNGase F labelled with phehylhydrazine and characterized by MALDI-MS/MS. This workflow is reported for the first time for this particular antibody and presents a valuable approach for the analysis of N-glycans on most antibodies and glycoproteins. |
