Hydrophilic Interaction Chromatography (HILIC)

Hydrophilic Interaction Chromatography (HILIC)

Hydrophilic interaction chromatography (HILIC) is a valuable analytical tool for biochemical research. CD BioGlyco has accumulated extensive experience in the application of HILIC to the analysis of glycosylation. Based on our extensive expertise and advanced research platform, we are confident to provide efficient and reliable technical support to our customers.


Characterization of protein glycosylation has significance for understanding protein function and role in various disease states. Glycosylation sites and the composition, branching, and length of glycan chains can affect the structure and function of proteins. This glycosylation information is important for understanding proteins used as therapeutic agents. Therefore, a variety of separation techniques have been developed to analyze and characterize glycans from glycoproteins, proteoglycans, and glycolipid conjugates.

The polarity of glycopeptides and oligosaccharides interact selectively with the polar stationary phase, which provides an opportunity for the application of HILIC in sample purification and analysis. HILIC has been successfully applied to several aspects of glycosylation analysis. PNGase F was used to perform glycan profile analysis of enzymatic glycan release, followed by derivatization with 2-aminobenzamide (2-AB) by HILIC-UHPLC, which is a powerful technique that can be used for the analysis of samples with well-known N-glycan profiles.
