WebGlycosylation of biotherapeutics can impact drug safety, efficacy, and stability, therefore it is often designated as a critical quality attribute (CQA) in biopharmaceutical development. 1 Given its sensitivity to upstream processing conditions, glycosylation also serves as a key indicator of process stability and robustness. 2 In addition to the … WebSCIEX Fast Glycan Labeling and Analysis delivers rapid glycan heterogeneity identification, capable of profiling your glycans in record time. Combining simplified sample preparation , rapid separations and automated glycan identification, you can make confident decisions quickly by running glycans up to two-times faster than HILIC - including ...
WebFeb 20, 2024 · A rapid and facile preparation of APTS-labeled N-glycans for routine glycan analysis. • A combination of ion-pair assited extration and HILIC-SPE was completed within 4 h. • The present method was well compatible with electrophoretic analysis with electrokinetic sample injection. Abstract WebJan 11, 2024 · HILIC-MS analysis involves the identification of each of the glycans by conversion of the retention time to Glucose Units (GU) ( Domann et al., 2007 ). The GU values of each of the glycans is a specific property of the fluorescent tag used for labeling, and therefore each tag will have a unique GU value for a particular glycan.
WebA high-resolution HILIC-MS/MS method was developed to analyze anthranilic acid derivatives of N-glycans released from human serum alpha-1-acid glycoprotein (AGP). The method was applied to samples obtained from 18 patients suffering from high-risk malignant melanoma as well as 19 healthy individuals. It enabled the identification of 102 … WebAccucore 150-Amide-HILIC, Core Enhanced Technology, amide HILIC, bovine fetuin glycans, HILIC, 150 Å pore size . Abstract.
