20100129843 | CHARACTERIZATION OF N-GLYCANS USING EXOGLYCOSIDASES - The present disclosure provides methods for analyzing structure and/or composition of N-glycans. Such methods often involve digestion of N-glycans with multiple exoglycosidases. In some embodiments, N-glycans are digested with multiple exoglycosidases simultaneously. In some embodiments, N-glycans are digested with multiple exoglycosidases sequentially. In some embodiments, methods in accordance with the present disclosure involve comparison of cleavage products of N-glycans that have been digested with multiple exoglycosidases simultaneously to N-glycans that have been digested with multiple exoglycosidases sequentially. | 05-27-2010 |
20100151499 | PROTEOLYTIC RELEASE OF GLYCANS - The present disclosure provides strategies for analyzing protein-linked glycans, and particularly for analyzing glycans on cell surface glycoproteins. | 06-17-2010 |
20100196940 | METHODS RELATED TO CELL SURFACE GLYCOSYLATION - The present disclosure provides methods for assessing the glycosylation of a target glycoprotein produced by a cell through analysis of cell-surface glycans on the cell. The present disclosure therefore teaches that glycosylation of cell surface proteins can serve as a proxy for glycosylation of other proteins. | 08-05-2010 |
20110213137 | ISOTOPICALLY-LABELED GLYCANS - The present disclosure provides methods of making isotopically-labeled glycans or a mixture of glycans (e.g., a glycan preparation) via reductive amination. Such methods are useful, for example, in the determination of the relative amounts of a glycan species present in two or more glycoprotein preparations using mass spectroscopy. In one aspect, the present disclosure provides a method of making an isotopically-labeled glycan by a glycan with an amine and an isotopically-labeled reducing agent to provide an isotopically-labeled aminated glycan. In certain embodiments, the amine is an isotopically-labeled amine. | 09-01-2011 |
20120264927 | METHODS FOR LABELING GLYCANS - Methods for labeling glycans that include a step of freeze-drying a labeled glycan preparation. The labeled glycan preparation is maintained in a substantially frozen state for the duration of the freeze-drying process. | 10-18-2012 |
20120329709 | PRODUCTION OF GLYCOPROTEINS - The present invention provides methods and materials by which glycosylation of glycoproteins can be regulated. Methods include the monitoring and regulation of parameters such that a glycoprotein having a desired product quality is obtained. | 12-27-2012 |
20130123126 | SELECTION AND USE OF HOST CELLS FOR PRODUCTION OF GLYCOPROTEINS - A method of making a glycoprotein having a selected glycostructure. | 05-16-2013 |
20130184180 | CHARACTERIZATION OF N-GLYCANS USING EXOGLYCOSIDASES - The present disclosure provides methods for analyzing structure and/or composition of N-glycans. Such methods often involve digestion of N-glycans with multiple exoglycosidases. In some embodiments, N-glycans are digested with multiple exoglycosidases simultaneously. In some embodiments, N-glycans are digested with multiple exoglycosidases sequentially. In some embodiments, methods in accordance with the present disclosure involve comparison of cleavage products of N-glycans that have been digested with multiple exoglycosidases simultaneously to N-glycans that have been digested with multiple exoglycosidases sequentially. | 07-18-2013 |
20130231255 | HIGH MANNOSE GLYCANS - Methods and compositions related to high mannose glycans are described. | 09-05-2013 |
20140112910 | MODIFIED GLYCOPROTEINS - Sulfated glycoproteins, and methods of making and using such sulfated glycoproteins, are described. | 04-24-2014 |
20140274911 | METHODS OF CELL CULTURE - Polypeptide preparations having target levels of glycans, and methods of producing such polypeptide preparations using ammonium and/or lysine, are described. | 09-18-2014 |
