Specific enrichment and glycosylation discrepancy profiling of cellular exosomes using a dual-affinity probe

Chem Commun (Camb). 2021 Jun 24;57(51):6249-6252. doi: 10.1039/d1cc01530c.

Abstract

A hydrophilic probe is employed to enrich exosomes from three kinds of cancer cells by TiO2-phosphate interaction and exosomal glycoproteins by hydrophilic interaction in succession. The probe performs efficiently in both the enrichment processes. And the analytical results confirm that unique exosomal glycoproteins can distinguish parent exosomes from others.
