WebMay 26, 2024 · LC-MS detection using more volatile solvents, such as when doing HILIC, or ERLIC (ion-pair normal phase), can be up to 100 times more sensitive than LC-MS RPC. Mobile Phases and Temperature Effects Polypeptides are generally more soluble in aqueous solvents than at high organic concentrations. Web• HILIC better resolved glycopeptide/peptide mixtures. • HILIC exhibited some potential to resolve O‐GalNAc modifications at variant sites (3 and 13) on the MUC5AC peptide sequence. • Additional glycopeptide/peptide pairs will be examined to improve the retention prediction for O‐HexNAcpeptide modifications. • Supported by NIH NIGMS GM093747.
