Abstract

A hierarchical Fe-ZSM-5 zeolite monolithic column was fabricated for immobilization of low abundance phosphoprotein through specific coordination between heteroatomic Fe in the framework of the zeolite with the phosphate group in the micro-environment of the protein. Compared to traditionally immobilized metal ion chromatography, this method could be directly manipulated and handily adapted for phosphoproteomics identification.
