WebThe optimized multidimensional detection offers increased confidence in glycan identification which can be further supported by an exoglycosidase digestion array (optional). Here we describe the PNGase F release of N-glycans from a typical IgG1 monoclonal antibody (mAb) with subsequent labeling with RapiFluor-MS™ for detection … WebHILIC was performed on 1 µL aqueous injections of 5 mg/mL trastuzumab using an ACQUITY UPLC Glycoprotein BEH Amide 300Å 1.7 µm Column heated to 80˚C. Sample was separated at a flow rate of 0.4 mL/min with aqueous (A) and acetonitrile (B) mobile phases containing 0.1% (v/v) TFA and 0.3% (v/v) HFIP.
WebFollowing HILIC-FLD analysis, routine glycan assignment is facilitated by Glucose Unit (GU) normalization, often through retention time calibration using a labelled dextran ladder. Through creation of a relevant GU retention library, glycan identification can be performed routinely, without the need for prior mass spectrometric analysis. WebJun 7, 2024 · The dried glycans were re-dissolved in 200–500 μL of water, loaded onto the home-made absorbent cotton HILIC, and dried in vacuum at 30 ℃ for 30 min. Salt ions and other impurities were removed by 20 mL gradient elution with 100% ACN + 0.1% TFA and 90% ACN/water (v/v) + 0.1% TFA, respectively.
WebMar 1, 2024 · Isolating glycans from complex biosamples is the basic and essential approach, the advanced separation and purification techniques based on HILIC materials could provide countless glycan species and remarkably enlarge the natural glycan libraries, which would promote the discovery of valuable glycan-receptors. WebApr 14, 2024 · Fluorescently labeled N-glycans were analyzed by HILIC-UHPLC-FLR on a Waters Acquity UPLC instrument (Waters, USA), which consisted of a quaternary solvent manager, a sample manager, and an FLR fluorescence detector set with excitation and emission wavelengths of 310 and 370 nm, respectively. Labeled N-glycans were …
