WebFeb 20, 2024 · Glycan analysis of erythropoiesis-stimulating agents Erythropoiesis stimulating agents (ESAs) are a group of therapeutic glycoproteins used to treat anaemia caused by chronic kidney disease or chemotherapy. A variety of ESA products are available in the European Union, including innovator, biosimilar and second-generation medicines. WebTo address these shortcomings, we have developed an N -glycan labeling reagent that provides enhanced fluorescence response and MS sensitivity for glycan detection and have also simplified the process of preparing a sample for analysis. The developed labeling reagent rapidly reacts with glycosylamines upon their release from glycoproteins.
WebN-glycosylation is a co- and post-translational modification of proteins in which carbohydrate moieties are attached to an asparagine residue of a polypeptide backbone. It is considered one of the most diverse modifications as there are numerous possible N-glycan structures, despite glycan biosynthesis not being template-driven . WebApr 14, 2024 · Salivary IgG N-glycans were analyzed by ultra-high-performance liquid chromatography based on hydrophilic interactions with fluorescence detection (HILIC-UHPLC-FLR). In addition, we compared IgG N-glycan profiles from saliva with those from plasma, assessed the stability of salivary IgG N-glycan profiles under different storage …
