WebDec 1, 2016 · Although HILIC SPE is efficient (reproducible and sensitive) for glycopeptide enrichment from mixtures, hydrophilic non-glycosylated peptides are also frequently co-enriched. This represents a particular problem for analysing complex samples as the co-enriched hydrophilic peptides can cause glycopeptide ion-suppression. WebApr 14, 2024 · Excess reagents were removed from the samples using hydrophilic interaction liquid chromatography–solid phase extraction (HILIC-SPE) as described in . For the HILIC-SPE step, an AcroPrepadv 1 mL 0.2 μm wwPTFE plate (Pall) was used as the stationary phase. The labeled glycans were eluted with ultrapure water and stored at − …
