WebHILIC or hydrophilic interaction liquid chromatography is a high-performance liquid chromatographic (HPLC) technique for separation of polar and hydrophilic compounds. Simply put, HILIC is a normal-phase type of separation but uses reversed-phase type eluents. WebSolid-phase extraction microtips are important devices in modern bioanalytics, as they allow miniaturized sample preparation for mass spectrometric analysis. Here we introduce the …

WebCardiolipin iSPE® HILIC Isolation Publication outlines a HILIC-based clean‐up method enabling complete separation of polar lipids containing four fatty acyl residues from non … WebHILIC SPE HILIC SPE has also been used to enrich glycopeptides from complex peptide mixtures such as proteolytic digests of serum, saliva and other body fluids. This approach has mostly been used to determine N-glycosylation sites of glycoproteins following glycan release10-12. The glycan release leaves a peptide
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. WebHILIC SPE can be used for glyco-profiling, i.e., for determining the glycan heterogeneity at one specific glycosylation site, for enrichment of glycopeptides from a complex mixture of peptides, as well as for pre-fractionation of complex samples at the protein or peptide level. In this chapter we present a straightforward HILIC SPE enrichment ...
WebBecause the separation mechanism in HILIC methods involves the adsorption of a water layer on the particle surface, it is very important to completely reestablish or “reset” this water layer in between injections to ensure retention time reproducibility. We recommend equilibration with a minimum of 10 column volumes starting when the ... WebGlycoWorks HILIC SPE offers a robust, reliable solution for cleanup and concentration of glycans from complex matrices. Its application during the sample preparation of 2-AB …
WebJun 7, 2024 · Glycosylation is one of the most common and complex protein post-translational modifications and plays a crucial role in many biological functions, such as immune recognition, signal transduction, cell adhesion, and tumour development [1].
