Immobilized metal affinity chromatography (IMAC) is a powerful method in phosphopeptide enrichment.However,the achievement of highly specific enrichment and sensitive detection of phosphopeptide by IMAC remains a big challenge since the lack of high specificity and large binding capacity of conventional IMAC materials.
