WebHILIC-UHPLC analysis of labeled N-glycans results in separation of the major glycans for both MabThera (Figure 2A) and Enbrel (Figure 2B). The fluorescence intensities of equivalent quantities of glycans loaded on column varies by the dye used for labeling (Figure 2 A inset). While retention time of labeled N-glycans is WebHILIC Overview. HILIC can be described as a variation of reversed phase chromatography performed using a polar stationary phase. The mobile phase employed is highly organic in …
WebFeb 15, 2024 · Although HILIC is now considered a standard approach for released glycan characterization, there are several technical hurdles that can be encountered when putting it to practice. One challenge is recovering and resolving certain acidic glycans during both sample preparation and chromatographic separations.
