Simultaneous Analysis of Sulfated and Phosphorylated Glycans by Serotonin-Immobilized Column Enrichment and Hydrophilic Interaction Chromatography.

Changes in the structures and quantities of sulfated glycans play important roles in inflammatory and neurological diseases and cancer. Therefore, sulfated glycans are expected to become diagnostic markers for a variety of diseases such as Alzheimer's disease and cancer. On the other hand, structural abnormalities in the phosphorylated glycans on lysosomal enzymes cause a number of lysosomal diseases, while novel phosphorylated glycans have been found in other proteins.
