Abstract:
Highly efficient and selective enrichment of glycopeptides from complex biosamples is vital prior to mass spectrometry analysis. In this work, a hydrophilic metal organic framework with free carboxylic groups (denoted as UiO-66-COOH) was synthesized in one step with binary ligands. Compared with pure UiO-66 with one ligand, UiO-66-COOH containing binary ligands demonstrated greater hydrophilicity and performed much better in selective enrichment of glycopeptides. The as-prepared material demonstrated excellent performance for selective enrichment of glycopeptides from tryptic digests of standard glycoproteins and practical biological samples.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
