ProteomicsAnion-Exchange Chromatography of Tryptic and Phosphopeptides: WAX vs. SAX and AEX vs. ERLIC
At a pH > 5, phosphopeptides have two negative charges per residue and are well-retained in anion-exchange chromatography. However, the peptides with one or two phosphate groups are not separated from the peptides with multiple Asp or Glu residues, which interfere with the identification of phosph...

ProteomicsAnalysis of Pancreatic Extracellular Matrix Protein Post-Translational Modifications via Electrostatic Repulsion-Hydrophilic Interaction Chromatography Coupled with Mass Spectrometry
The pancreas is a vital organ with digestive and endocrine roles, and diseases of the pancreas affect millions of people yearly. A better understanding of the pancreas proteome and its dynamic post-translational modifications (PTMs) is necessary to engineer higher fidelity tissue analogues for use ...

ProteomicsPeptide Retention Time Prediction for Electrostatic Repulsion-Hydrophilic Interaction Chromatography
Electrostatic Repulsion-Hydrophilic Interaction Chromatography (ERLIC) is a legacy separation tools developed by Dr. Andrew Alpert and has been used for developing unique separation methods of hydrophilic compounds, including peptides. We employed a proteomics-derived ~170,000 peptide retention data...

ProteomicsCounterion Optimization Dramatically Improves Selectivity for Phosphopeptides and Glycopeptides in Electrostatic Repulsion-Hydrophilic Interaction Chromatography (ERLIC)
A well-hydrated counterion can selectively and dramatically increase retention of a charged analyte in hydrophilic interaction chromatography (HILIC). The effect is enhanced if the column is charged, as in electrostatic repulsion-hydrophilic interaction chromatography (ERLIC). This combination was...

ProteomicsHighly sensitive phosphoproteomics by tailoring solid-phase extraction to electrostatic repulsion-hydrophilic interaction chromatography
The dataset contains the data of key experiments for developing a novel and highly sensitive bottom-up phosphoproteomics strategy termed ERLIC-SCX/RP-LC-MS. We compared two SPE types (RP, SCX) for an ERLIC run with 7 fractions. The results were used to design a workflow for highly sensitive bottom-u...

ProteomicsFinding the Sweet Spot in ERLIC Mobile Phase for Simultaneous Enrichment of N-Glyco and Phosphopeptides
Simultaneous enrichment of glyco- and phospho- peptides will benefit the studies of biological processes regulated by these post-translational modifications (PTMs). It will also reveal potential crosstalk between these two ubiquitous PTMs. Unlike custom designed multifunctional solid phase extractio...
