英文摘要as a naturally hydrophilic peptide, glutathione was facilely immobilized onto silica surface to obtain a novel hydrophilic interaction/cation-exchange mixed-mode chromatographic stationary phase (click te-gsh) via copper-free "thiol-ene" click chemistry. the resulting material was characterized by solid state c-13/cp mas nmr and elemental analysis. the measurement of zeta-potential indicated the cation-exchange characteristics and adjustable surface charge density of click te-gsh material. the influence of acetonitrile content and ph value on the retention of ionic compounds was investigated for understanding the chromatographic behaviors. the results demonstrated that click te-gsh column could provide both hydrophilic and cation-exchange interaction. taking advantage of the good hydrophilicity and inherent cation-exchange characteristics of click te-gsh material, the resolution of neutral fructosan with high degree of polymerization (dp), basic chitooligosaccharides and strongly acidic carrageenan oligosaccharides was successfully realized in hydrophilic interaction chromatography (hilic), hydrophilic interaction/cation-exchange mixed-mode chromatography (hilic/cex), cation-exchange chromatography (cex) and electrostatic repulsion/hydrophilic interaction chromatography (erlic). on the other hand, the separation of standard peptides varying in hydrophobicity/hydrophilicity and charge was achieved in both cex and hilic/cex mode with high efficiency and distinct selectivity. to further demonstrate the versatility and applicability of click te-gsh stationary phase, the separation of a human serum albumin (hsa) tryptic digest was performed in hilic/cex mode. peptides were adequately resolved and up to 86 hsa peptides were identified with sequence coverage of 85%. the results indicated the good potential of click te-gsh material in glycomics and proteomics.
