Hilic glycan analysis
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 … WebIn this application note, a rapid method for analysis of glycans is presented. This method describes deglycosylation of glycoproteins aided by an enzyme-friendly surfactant (RapiGest SF), sample cleanup using a HILIC chromatography performed in a 96-well microtiter plate (MassPREP HILIC µElution Plate), and MALDI MS analysis of the resulting glycans.

WebN-linked glycans are easily released from proteins using PNGaseF. Upon release, glycans do not contain a chromophore so they must be derivatized prior to analysis with a suitable label which provides fluoresce and mass spectrometric response. The use of 2-AB is the most common label for HILIC-FLR-MS analysis and was selected for this study. WebAnalysis of the glycan moieties attached to a mAb is commonly conducted by enzymatic deglycosylation using N-Glycosidase F (PNGase F) to cleave ...
