WebDec 24, 2015 · Zwitterionic hydrophilic interaction chromatography (ZIC-HILIC) solid-phase extraction (SPE) combined with direct-infusion nanoESI mass spectrometry (MS) and tandem MS/MS is a well-suited method for the analysis of protein N-glycosylation.A site-specific characterization of N-glycopeptides is achieved by the combination of proteolytic …
WebDec 30, 2013 · The extraction solution could be directly applied to the HILIC SPE without the solvent evaporation step, which further simplified the analysis processes. And CKs was enriched and purified with one-step pretreatment procedure that significantly improved the analysis efficiency. Subsequently, CKs were separated by RPLC, orthogonal to the HILIC ... WebSolid-phase extraction microtips are important devices in modern bioanalytics, as they allow miniaturized sample preparation for mass spectrometric analysis. Here we introduce the use of cotton wool for the preparation of filter-free HILIC SPE microtips. To this end, pieces of cotton wool pads (approximately 500 μg) were packed into 10 μL pipet tips. The …
WebiHILIC columns are designed for the separation of polar and hydrophilic compounds using Hydrophilic Interaction Liquid Chromatography (HILIC). Four different column chemistries with complementary selectivity provide the power to maximize the separation selectivity and resolution. iHILIC columns have been used by the scientists around the world in various … 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
