Researchers from University of Pannonia Report New Studies and Findings in the Area of Carbohydrate Research

May 27, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Life Science Research. According to news reporting originating from Veszprem, Hungary, by NewsRx correspondents, research stated, "The IgG N-glycome provides sufficient complexity and information content to serve as an excellent source for biomarker discovery in mammalian health. Since oligosaccharides play a significant role in many biological processes it is very important to understand their structure."

Our news editors obtained a quote from the research from the University of Pannonia, "The glycosylation is cell type specific as well as highly variable depending on the species producing the IgG. We evaluated the variation of N-linked glycosylation of human, bovine, ovine, equine, canine and feline IgG using three orthogonal glycan separation techniques: hydrophilic interaction liquid chromatography (HILIC)-UPLC, reversed phase (RP)-UPLC and capillary electrophoresis with laser induced fluorescence detection (CE-LIF). The separation of the glycans by these high resolution methods yielded different profiles due to diverse chemistries. However, the % abundance of structures obtained by CE-LIF and HILIC-UPLC were similar, whereas the analysis by RP-UPLC was difficult to compare as the structures were separated by classes of glycans (highly mannosylated, fucosylated, bisected, fucosylated and bisected) resulting in the co-elution of many structures."

According to the news editors, the research concluded: "The IgGs from various species were selected due to the complexity and variation in their N-glycan composition thereby highlighting the complementarity of these separation techniques."
