摘要

Novel molecularly imprinted polymers (MIPs) designed to bind the side chain of phosphotyrosine can be used as artificial receptors for affinity-based enrichment of proteolytic peptides. In comparison with general enrichment methods for phosphorylated peptides such as TiO(2)-based methods, the pTyr-imprinted polymers offered high selectivity for pTyr-containing peptides down to the low fmol level. This suggests MIPs as a new tool for affinity-based proteomics.
